UTRS3080

Preliminary

CMOS IC

FAIL-SAFE, 500KBPS, RS-485 /

RS-422 TRANSCEIVERS WITH

±12KV ESD-PROTECTED



DESCRIPTION

The UTC UTRS3080 high-speed transceivers for RS-485/RS-422

communication contain one driver and one receiver. The device

features fail-safe circuitry, which guarantees a logic-high receiver

output when the receiver inputs are open or shorted. This means that

the receiver output will be logic high if all transmitters on a terminated

bus are disabled (high impedance). The UTC UTRS3080 features

reduced slew-rate drivers that minimize EMI and reduce reflections

caused by improperly terminated cables, allowing error-free data

transmission up to 500kbps.

The transceiver typically draws 375µA of supply current when

unloaded or when fully loaded with the drivers disabled.

A device has a 1/8-unit-load receiver input impedance that allows

up to 256 transceivers on the bus.



FEATURES

* True fail-safe receiver while maintaining EIA/TIA-485 compatibility

* Enhanced slew-rate limiting facilitates Error-Free data transmission

* 5.0V single power supply

* 1µA low-current shutdown mode

* Allow up to 256 transceivers on the Bus

* HBM ±12kV ESD protection for Drive / Receiver

* Driver short circuit current limit

* Thermal shutdown for overload protection
