The ST485EBDR is a low power Transceiver for RS-485 and RS-422 communication. Each driver output and receiver input is protected against ±15kV electrostatic discharge (HBM) (ESD) shocks, without latch-up. These parts contain one driver and one receiver in half duplex configuration. Driver is short-circuiting current limited and is protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-impedance state. It is designed for bi-directional data communications on multipoint bus transmission lines.
Driver maintains high impedance in 3-state or with the power OFF
Current limiting and thermal shutdown for driver overload protection
Allows up to 256 transceivers on the bus
70mV Typical input hysteresis
30ns Propagation delay and 5ns skew
ESD sensitive device, take proper precaution while handling the device.
