数据手册.pdf？ 5KV ESD保护，低功耗RS - 485 / RS - 422收发器 ?5KV ESD PROTECTED, LOW POWER RS-485/RS-422 TRANSCEIVER
Description
The ST485E 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 latch-up. These parts contain one driver and one receiver in half duplex configuration.
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 typical input hysteresis
■ 30ns propagation delay, 5ns skew
■ Operates 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 64 transceivers on the bus
