HIN201 thru HIN213
+5V Powered RS-232
Transmitters/Receiverswith0.1Microfarad
External Capacitors
The HIN201-HIN213 family of RS-232 transmitters/receivers
interface circuits meet all ElA RS-232E and V.28
specifications, and are particularly suited for those
applications where ±12V is not available. They require a
single +5V power supply (except HIN201) and feature
onboard charge pump voltage converters which generate
+10V and -10V supplies from the 5V supply. The HIN203
and HIN205 require no external capacitors and are ideally
suited for applications where circuit board space is critical.
The family of devices offers a wide variety of RS-232
transmitter/receiver combinations to accommodate various
applications (see Selection Table).
The HIN205, HIN206, HIN211 and HIN213 feature a low
power shutdown mode to conserve energy in battery
powered applications. In addition, the HIN213 provides two
active receivers in shutdown mode allowing for easy
“wakeup” capability.
The drivers feature true TTL/CMOS input compatibility, slew
rate-limited output, and 300Ω power-off source impedance.
The receivers can handle up to ±30V input, and have a 3kΩ
to 7kΩ input impedance. The receivers also feature
hysteresis to greatly improve noise rejection.

Pin Descriptions
PIN FUNCTION
VCC Power Supply Input 5V ±10%, 5V ±5% (HIN207, HIN203, and HIN205).
V+ Internally generated positive supply (+10V nominal), HIN201 requires +9V to +13.2V.
V- Internally generated negative supply (-10V nominal).
GND Ground Lead. Connect to 0V.
C1+ External capacitor (+ terminal) is connected to this lead.
C1- External capacitor (- terminal) is connected to this lead.
C2+ External capacitor (+ terminal) is connected to this lead.
C2- External capacitor (- terminal) is connected to this lead.
TIN Transmitter Inputs. These leads accept TTL/CMOS levels. An internal 400kΩpull-up resistor to VCC is connected to each lead.
TOUT Transmitter Outputs. These are RS-232 levels (nominally ±10V).
RIN Receiver Inputs . These inputs accept RS-232 input levels. An internal 5kΩpull-down resistor to GND is connected to each input.
ROUT Receiver Outputs. These are TTL/CMOS levels.
EN, EN Enable Input. This is an active low input which enables the receiver outputs. With EN = 5V, (HIN213 EN = 0V), the outputs are placed
in a high impedance state.
SD, SD Shutdown Input. With SD = 5V (HIN213 SD = 0V), the charge pump is disabled, the receiver outputs are in a high impedance state
(except R4 and R5 of HIN213) and the transmitters are shut off.
NC No Connect. No connections are made to these leads.

Detailed Description
The HIN201 thru HIN213 family of RS-232
transmitters/receivers are powered by a single +5V power
supply (except HIN201), feature low power consumption,
and meet all ElA RS232C and V.28 specifications. The
circuit is divided into three sections: The charge pump,
transmitter, and receiver.
Charge Pump
An equivalent circuit of the charge pump is illustrated in
Figure 1. The charge pump contains two sections: the
voltage doubler and the voltage inverter. Each section is
driven by a two phase, internally generated clock to generate
+10V and -10V. The nominal clock frequency is 125kHz.
During phase one of the clock, capacitor C1 is charged to
VCC. During phase two, the voltage on C1 is added to VCC,
producing a signal across C3 equal to twice VCC. During
phase two, C2 is also charged to 2VCC, and then during
phase one, it is inverted with respect to ground to produce a
signal across C4 equal to -2VCC. The charge pump accepts
input voltages up to 5.5V. The output impedance of the
voltage doubler section (V+) is approximately 200Ω, and the
output impedance of the voltage inverter section (V-) is
approximately 450Ω. A typical application uses 0.1µF
capacitors for C1-C4, however, the value is not critical.
Increasing the values of C1 and C2 will lower the output
impedance of the voltage doubler and inverter, increasing
the values of the reservoir capacitors, C3 and C4, lowers the
ripple on the V+ and V- supplies.
During shutdown mode (HIN205, HIN206 and HIN211,
SD = VCC, HIN213, SD = 0V) the charge pump is turned off,
V+ is pulled down to VCC, V- is pulled up to GND, and the
supply current is reduced to less than 10µA. The transmitter
outputs are disabled and the receiver outputs (except for
HIN213, R4 and R5) are placed in the high impedance state.
Transmitters
The transmitters are TTL/CMOS compatible inverters which
translate the inputs to RS-232 outputs. The input logic
threshold is about 26% of VCC, or 1.3V for VCC = 5V. A logic
1 at the input results in a voltage of between -5V and V- at
the output, and a logic 0 results in a voltage between +5V
and (V+ - 0.6V). Each transmitter input has an internal
400kΩ pullup resistor so any unused input can be left
unconnected and its output remains in its low state. The
output voltage swing meets the RS-232C specifications of
±5V minimum with the worst case conditions of: all
transmitters driving 3kΩ minimum load impedance, VCC =
4.5V, and maximum allowable operating temperature. The
transmitters have an internally limited output slew rate which
is less than 30V/µs. The outputs are short circuit protected
and can be shorted to ground indefinitely. The powered
down output impedance is a minimum of 300Ω with ±2V
applied to the outputs and VCC = 0V.
Receivers
The receiver inputs accept up to ±30V while presenting the
required 3kΩto 7kΩinput impedance even if the power is off
(VCC = 0V). The receivers have a typical input threshold of
1.3V which is within the ±3V limits, known as the transition
region, of the RS-232 specifications. The receiver output is
0V to VCC. The output will be low whenever the input is
greater than 2.4V and high whenever the input is floating or
driven between +0.8V and -30V. The receivers feature 0.5V
hysteresis (except during shutdown) to improve noise
rejection. The receiver Enable line (EN, on HIN205, HIN206
and HIN211, EN on HIN213) when unasserted, disables the
receiver outputs, placing them in the high impedance mode.
The receiver outputs are also placed in the high impedance
state when in shutdown mode (except HIN213 R4 and R5).
HIN213 Operation in Shutdown
The HIN213 features two receivers, R4 and R5, which
remain active in shutdown mode. During normal operation
the receivers propagation delay is typically 0.5µs. This
propagation delay may increase slightly during shutdown.
When entering shut down mode, receivers R4 and R5 are
not valid for 80µs after SD = VIL. When exiting shutdown
mode, all receiver outputs will be invalid until the charge
pump circuitry reaches normal operating voltage. This is
typically less than 2ms when using 0.1µF capacitors.

Application Information
The HIN2XX may be used for all RS-232 data terminal and
communication links. It is particularly useful in applications
where ±12V power supplies are not available for
conventional RS-232 interface circuits. The applications
presented represent typical interface configurations.
A simple duplex RS-232 port with CTS/RTS handshaking is
illustrated in Figure 9. Fixed output signals such as DTR
(data terminal ready) and DSRS (data signaling rate select)
is generated by driving them through a 5kW resistor
connected to V+.
In applications requiring four RS-232 inputs and outputs
(Figure 10), note that each circuit requires two charge pump
capacitors (C1 and C2) but can share common reservoir
capacitors (C3 and C4). The benefit of sharing common
reservoir capacitors is the elimination of two capacitors and
the reduction of the charge pump source impedance which
effectively increases the output swing of the transmitters.
