Description
The ST485E is al low power transceiver for RS-485 and RS-422 communication. Each driver output and receiver input is protected against ±15KV electrostatic discharge (H.B.M.) ±8KV (IEC-1000-4-2 contact discharge) shocks, without latchup. These parts contain one driver and one receiver.

General features
■ Low quiescent current: 300µA
■ Designed for RS-485 interface application
■ -7V to 12V common mode input voltage range
■ Driver maintains high impedance in 3-state or with the power OFF
■ 70mV tipycal input hysteresis
■ 30ns propagation delay, 5ns skew
■ Operate from a single 5V supply
■ Current limiting and thermal shutdown for driver overload protection
■ ESD protection:
  – ±15KV (H.B.M.)
  – ±8KV (IEC-1000-4-2 contact discharge)
■ Allows up to 256 transceivers on the bus
