XR33052/XR33053/XR33055/XR33058 60V Fault Tolerant 3.0V to 5.5V RS-485/RS-422 Transceivers Description The XR33052, XR33053, XR33055, and XR33058 (XR3305x) are a family of high performance RS-485/RS-422 devices designed for improved performance in noisy industrial environments and increased tolerance to system faults. The analog bus pins can withstand direct shorts up to 60V and are protected against ESD events up to 15kV HBM. An extended 25V common mode operating range allows for more reliable operation in noisy environments. The XR3305x receivers include full fail-safe circuitry, guaranteeing a logic-high receiver output when the receiver inputs are open, shorted or undriven. The XR33052/53/55 receiver input impedance is at least 120k (1/10 unit load), allowing more than 320 devices on the bus. The XR33058 receiver input impedance is at least 30K (1/2.5 unit load), allowing more than 80 devices on the bus. The driver is protected by short circuit detection as well as thermal shutdown and maintains high impedance in shutdown or when powered off. The DE and RE pins include hot swap circuitry to prevent false transitions on the bus during power up or live insertion and can enter a 1nA low current shutdown mode for extreme power savings. The XR33052/55/58 are half-duplex transceivers offered in an 8-pin NSOIC package and operates at a maximum data rates of 250k, 1M and 20Mbps. The XR33053 is a full-duplex transceiver offered in a 14-pin NSOIC package and operates at a maximum data rate of 1 Mbps.

Receiver Enable and Disable Test Circuits and Timing Diagrams REV2B 14/18 XR33052/XR33053/XR33055/XR33058 Applications Information (Continued) The XR3305x RS-485/RS-422 devices are part of Exar's high performance serial interface product line. The analog bus pins can survive direct shorts up to 60V and are protected against ESD events up to 15kV. Enhanced Failsafe Ordinary RS-485 differential receivers will be in an indeterminate state whenever the data bus is not being actively driven. The enhanced failsafe feature of the XR3305x guarantees a logic-high receiver output when the receiver inputs are open, shorted or when they are connected to a terminated transmission line with all drivers disabled. In a terminated bus with all transmitters disabled, the receivers' differential input voltage is pulled to 0V by the termination. The XR3305x interprets 0V differential as a logic high with a minimum 50mV noise margin while maintaining compliance with the RS-485 standard of 200mV. Although the XR3305x does not need failsafe biasing resistors, it can operate without issue if biasing is used. Hot Swap Capability When VCC is first applied, the XR3305x holds the driver enable and receiver enable inactive for approximately 10s. During power ramp-up, other system ICs may drive unpredictable values or tristated lines may be influenced by stray capacitance. The hot swap feature prevents the XR3305x from driving any output signal until power has stabilized. After the initial 10s, the driver and receiver enable pins are weakly pulled to their disabled states (low for DE, high for RE) until the first transition. After the first transition, the DE and RE pins operate as high impedance inputs. If circuit boards are inserted into an energized backplane (commonly called "live insertion" or "hot swap") power may suddenly be applied to all circuits. Without the hot swap capability, this situation could improperly enable the transceiver's driver or receiver, driving invalid data onto shared buses and possibly causing driver contention or device damage. Driver Output Protection Two mechanisms prevent excessive output current and power dissipation caused by faults or by bus contention. First, a driver current limit on the output stage provides immediate protection against short circuits over the whole common-mode voltage range. Second, a thermal shutdown circuit forces the driver outputs into a high-impedance state if junction temperature becomes excessive. rise and fall times are shorter than the round-trip signal propagation time. Higher output drivers may allow longer cables to be used. 15kV HBM ESD Protection (Unpowered Part) ESD protection structures are incorporated on all pins to protect against electrostatic discharges encountered during handling and assembly. The driver outputs and receiver inputs of the XR3305x family have extra protection against static electricity. Exar uses state-of-the-art structures to protect these pins against ESD damage: 15kV 4kV HBM for bus pins to GND HBM for all other pins ESD Test Conditions ESD performance depends on a variety of conditions. Contact Exar for a reliability report that documents test setup, methodology and results. Maximum Number of Transceivers on the Bus The standard RS-485 receiver input impedance is 12k (1 unit load). A standard driver can drive up to 32 unit loads. The XR33052/53/55 transceiver has a 1/10th unit load receiver input impedance of 120k, allowing up to 320 transceivers to be connected in parallel on a communication line. The XR33058 receiver input impedance is a least 30K (1/2.5 unit load), allowing more than 80 devices on the bus. Any combination of the XR3305x's and other RS-485 transceivers up to a total of 32 unit loads may be connected to the line. Low Power Shutdown Mode Low power shutdown mode is initiated by bringing both RE high and DE low simultaneously. While in shutdown devices draw less than 1A of supply current. DE and RE may be tied together and driven by a single control signal. Devices are guaranteed not to enter shutdown if RE is high and DE is low for less than 50ns. If the inputs are in this state for at least 600ns, the parts will enter shutdown. Enable times tZH and tZL apply when the part is not in low power shutdown state. Enable times tZH(SHDN) and tZL(SHDN) apply when the parts are shutdown. The driver and receiver take longer to become enabled from low power shutdown tZH(SHDN) and tZL(SHDN) than from driver or receiver disable mode (tZH and tZL). Line Length The RS-485/RS-422 standard covers line lengths up to 4000ft. Maximum achievable line length is a function of signal attenuation and noise. Termination prevents signal reflections by eliminating the impedance mismatches on a transmission line.
