Low quiescent current: 300 µA 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-8Description
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 µA (typ.) of supply current when unloaded or fully loaded with disabled drivers. It operates from a single 5 V supply. Table 1. Device summary
