General Description
The HV2802 and HV2902 are low-charge injection,
32-channel, high-voltage analog switches intended for
use in applications requiring high-voltage switching
controlled by low-voltage control signals, such as
medical ultrasound imaging, driving piezoelectric
transducers and printers. The HV2902 has integrated
bleed resistors which eliminate voltage build-up on
capacitive loads such as piezoelectric transducers.
Input data are shifted into a 32-bit shift register that can
then be retained in a 32-bit latch. To reduce any
possible clock feedthrough noise, the latch enable bar
should be left high until all bits are clocked in. Data are
clocked in during the rising edge of the clock. Using the
HVCMOS technology, this device combines
high-voltage bilateral DMOS switches and low-power
CMOS logic to provide efficient control of high-voltage
analog signals.
The device is suitable for various combinations of
high-voltage supplies, e.g., VPP/VNN: +40V/-160V,
+100V/-100V and +160V/-40V.

multiplexing a piezoelectric transducer array in a probe
to multiple channel transmitters (Tx) arrays in a medical
ultrasound system.
Figure 4-1 shows a typical medical ultrasound image
system comprising 64-channels of transmit pulsers,
64-channels of receivers (LNA and ADC) and
64-channels of T/R switches connecting to 192
elements of an ultrasound transducer probe via a
high-voltage analog switch array.
FIGURE 4-1: Typical Med ical Ultrasou nd Imag ing Sys tem .
The HV2802/HV2902 devices are comprised of two
main circuitries:
• A low-power CMOS digital serial interface
powered by VDD to control the high-voltage
analog switches
• High-voltage bilateral analog switch.
High-voltage supplies VPP and VNN are needed by the
high-voltage level translation circuitry to control the
states of the output high-voltage analog switches. In
addition, each high-voltage analog switch can be
independently controlled because each switch is
controlled via a corresponding latch. A 32-bit shift
register and 32 latches allow the user to serially load
data into the registers, and after completion, to load the
data onto the latches that control the states of the
high-voltage analog switches.
The HV2802/HV2902 have a digital serial interface
consisting of logic signals, Data In (DIN), Clock (CLK),
Data Out (DOUT), Latch Enable (LE) and Clear (CLR).
The digital circuits are supplied by VDD and either a
3.3V or a 5V logic can be used. With a VDD = 5V supply,
the serial clock frequency can operate up to 20 MHz.
The data is shifted into the shift registers on the rising
edge (low-to-high transition) of the clock. The switch
configuration bit of SW31 is shifted in first and the
switch configuration bit of SW0 is shifted in last. To
avoid clock feedthrough, the latch enable input (LE)
should remain high while the 32-bit data-in signal is
shifted into the 32-bit register. After the valid 32-bit data
complete shifting into the shift registers, the high-to-low
transition of the LE signal transfers the contents of the
shift register into the latches. Finally, setting the LE high
again allows all the latches to keep the current state,
while new data can now be shifted into the shift
registers without upsetting the latches.
It is recommended to change all the latch states at the
same time through this method to avoid possible clock
feedthrough noise. See Figure 4-2 for details.

HV2802/HV2902
FIGURE 4-2: Latch Enable Timing Waveforms.
When the CLR input is set high, all 32 latches are
cleared of the data. Consequently, all the high-voltage
switches are set to off state. However, the CLR signal
does not affect the contents of the shift register, so the
shift register can operate independently of the CLR
signal. Hence, after the CLR input is set low, the shift
register would still retain the previous data.
The serial input interface of the HV2802/HV2902
allows multiple devices to daisy-chain together. In this
configuration, DOUT of a HV2802/HV2902 device is
connected to the DIN of the subsequent device, and so
forth. The last DOUT of the daisy-chained
HV2802/HV2902 can either be floating or fed back to
an FPGA to check the previously stored shift register
data. To control all the high-voltage analog switch
states in daisy-chained N devices, N times 32 clocks
and N times 32 bits of data are shifted into shift
registers, while LE remains high and CLR remains low.
After all N times 32 bits of data finish shifting in, the
high-to-low transition of the LE transfers the data from
all N times 32-bit shift registers to N times 32 latches
simultaneously. Consequently, all N times 32
high-voltage analog switches change states
simultaneously.
It is recommended that 0.1 uF ceramic decoupling
capacitors, with the appropriate voltage ratings, be
connected between GND and the other supplies (VDD,
VPP and VNN). These decoupling capacitors should be
placed as close as possible to the device.
The HV2802/HV2902 devices do not have a specific
power up/down sequence. During the power up/down
period, all the analog switch inputs should be within the
VPP and VNN range or floating. The rise time and fall
time of the power supplies, VDD, VPP and VNN, should
be greater than 1 ms. Violating the rise time or fall time
requirement on the power supplies may cause
malfunction such as latch-up or even permanent
damage of the device.
The HV2902 device has 35 k integrated bleed
resisters connected from all the analog switch
terminals A and B to RGND. These bleed resisters
eliminate voltage build-up on capacitive loads such as
piezoelectric transducers. The HV2802 device does
not have integrated bleed resistors.
