RS-485 и RS-422 ST485EBDR

IC , RS485/ RS422 TRX, LO-PWR, 8-SO

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
