SN65176BP, Дифференциальный приемопередатчик шины RS-485The SN65176BP is a Differential Bus Transceiver designed for bidirectional data communication on multipoint bus transmission lines. It is designed for balanced transmission lines and meets ANSI standards TIA/EIA-422-B and TIA/EIA-485-A and ITU recommendations V.11 and X.27. The SN65176B device combines a 3-state differential line driver and a differential input line receiver, both of which operate from a single 5V power supply. The driver and receiver have active-high and active-low enables, respectively, that can be connected together externally to function as a direction control. The driver differential outputs and the receiver differential inputs are connected internally to form differential input/output (I/O) bus ports that are designed to offer minimum loading to the bus when the driver is disabled or VCC=0. This port features wide positive and negative common-mode voltage ranges, making the device suitable for party-line applications., 3-state driver and receiver outputs, Individual driver and receiver enables, Wide positive and negative input/output bus voltage ranges, Thermal shutdown protection, Driver positive and negative current limiting, Designed for multipoint transmission on long bus lines in noisy environments, Operate from single 5V supply, ±60mA Maximum driver output capability, 12kR Minimum receiver input impedance, ±200mV Receiver input sensitivity, 50mV Typical receiver input hysteresis, 150°C Operating virtual junction temperature
