UTRS3085

DESCRIPTION 

The UTC UTRS3085 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 UTRS3085 offer higher 

driver output slew-rate limits, allowing transmission up to 2.5Mbps. 

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 Transmitter Output 

* Driver short circuit current limit. 

* Thermal shutdown for overload protection.
