SN75176A SLLS100C – JUNE 1984 – REVISED OCTOBER 2022 SN75176A Differential Bus Transceiver 1 Features Bidirectional Transceiver Meets or Exceeds the Requirements of ANSI Standards EIA/TIA-422-B and ITU Recommendations V.11 Designed for Multipoint Transmission on Long Bus Lines in Noisy Environments 3-State Driver and Receiver Outputs Individual Driver and Receiver Enables Wide Positive and Negative Input/Output Bus Voltage Ranges Driver Output Capability ±60 mA Max Thermal-Shutdown Protection Driver Positive-Current Limiting and NegativeCurrent Limiting Receiver Input Impedance 12 kΩ Min Receiver Input Sensitivity ±200 mV Receiver Input Hysteresis 50 mV Typ Operates From Single 5-V Supply Lower Power Requirements 2 Applications Low Speed RS485 communication (5 Mbps or less) For 10 Mbps, use SN75176B 3 Description The SN75176A differential bus transceiver is a monolithic integrated circuit designed for bidirectional data communication on multipoint bus-transmission lines. It is designed for balanced transmission lines and meets ANSI Standard EIA/TIA-422-B and ITU Recommendation V.11. The SN75176A combines a 3-state differential line driver and a differential input line receiver, both of which operate from a single 5-V power supply. The driver and receiver have active-high and activelow enables, respectively, that can be externally connected together to function as a direction control. The driver differential outputs and the receiver differenti...
