Product Summary

The ST485ECN is a 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.) (ESD) shocks, without latcup. These parts contain one driver and one receiver in half duplex configuration. This transceiver draw 300µA (typ.) of supply current when unloaded or fully loaded with disabled drivers. It operates from a single 5V supply. The ST485ECN is designed for bi-directional data communications on multipoint bus transmission
line (half-duplex applications).

Parametrics

ST485ECN absolute maximum ratings: (1)Supply Voltage: 7 V; (2)Control Input Voltage (RE, DE): -0.5 to (VCC + 0.5) V; (3)Driver Input Voltage (DI): -0.5 to (VCC + 0.5) V; (4)Driver Output Voltage (A, B): ± 14 V; (5)Receiver Input Voltage (A, B): ± 14 V; (6)Receiver Output Voltage (RO): -0.5 to (VCC + 0.5) V.

Features

ST485ECN features: (1)low quiescent current: 300μA; (2)designed for RS-485 interface applications; (3)-7V to 12V common mode input voltage range; (4)70mV typical input hysteresis; (5)30ns propafation delays, 5ns skew; (6)allows up to 64 transceivers on the bus.
