■ 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
■ Operate from a single 5 V supply
■ Current limiting and thermal shutdown for driver overload protection
■ Allows up to 64 transceivers on the bus
Description
The ST485 is al low power transceiver for RS-485 and RS-422 communication. Each part contains one driver and one receiver. This transceiver draw 300 µA (typ.) of supply current when unloaded or fully loaded with disabled drivers. It operates from a single 5 V supply.
Driver is short-circuit current limited and is protected against excessive power dissipation by thermal shutdown circuitry that placed the driver outputs into a high-impedance state. The ST485 is designed for bi-directional data communications on multipoint bus transmission line (half-duplex applications).
The ST485 is available in three temperature range: commercial (0 °C to 70 °C), industrial (-40 °C to 85 °C) and automotive (-55 °C to 125 °C).
