ST485 Low power RS-485/RS-422 transceiver General features I I I I I I I I I Low quiescent current: 300mA 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 tipycal input hysteresis 30ns propagation delay, 5ns skew Operate from a single 5V supply Current limiting and thermal shutdown for driver overload protection Allows up to 64 transceivers on the bus DIP-8 SO-8 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 300mA (typ.) of supply current when unloaded or fully loaded with disabled drivers. It operates from a single 5V 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 applciations). The ST485 is available in three temperature range: commercial (0°C to 70°C), industrial (40°C to 850°C) and automotive (-55°C to 125°C) Order code Part number ST485CN ST485BN ST485XN ST485CD ST485BD ST485CDR ST485BDR ST485XDR Temperature range 0 to 70 °C -40 to 85 °C -55 to 125 °C 0 to 70 °C -40 to 85 °C 0 to 70 °C -40 to 85 °C -55 to 125 °C Package DIP-8 DIP-8 DIP-8 SO-8 (Tube) SO-8 (Tube) SO-8 (Tape & reel) SO-8 (Tape & reel) SO-8 (T……
