ST485EB ST485EC - ST485EX
±15 kV ESD protected, low power RS-485/RS-422 transceiver
Features
■ Low quiescent current: 300 µA ■ Designed for RS-485 interface application ■ - 7 V to 12 V common mode input voltage range ■ Driver maintains high impedance in 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) – ± 8 kV (IEC-1000-4-2 contact discharge) ■ Allows up to 256 transceivers on the bus
Description
SO-8
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.
