Preliminary
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.
