Features

Low quiescent current: 300 A Designed for RS-485 interface application 12 V common mode input voltage range Driver maintains high impedance 3-state or with the power OFF 70 mV typical input hysteresis 30 ns propagation delay, 5 ns skew Operates from a single 5 V supply Current limiting and thermal shutdown for driver overload protection ESD protection: 15 kV (HBM) kV (IEC-1000-4-2 contact discharge) Allows to 256 transceivers on the bus Driver is short-circuit current limited and is protected against excessive power dissipation by thermal shutdown circuitry that place the driver outputs into a high-impedance state. The ST485E is designed for bi-directional data communications on multipoint bus transmission lines (half-duplex applications). SO-8

Description

The is a low power transceiver for RS485 and RS-422 communication. Each driver output and receiver input is protected against 15 kV electrostatic discharge (HBM) (ESD) shocks, without latch-up. These parts contain one driver and one receiver in half duplex configuration. This transceiver draws 300 A (typ.) of supply current when unloaded or fully loaded with disabled drivers. It operates from a single 5 V supply. Table 1. Device summary
