DESCRIPTION
●The SN55LBC180, SN65LBC180 and SN75LBC180 differential driver and receiver pairs are monolithic
●integrated circuits designed for bidirectional data communication over long cables that take on the
●characteristics of transmission lines. They are balanced, or differential, voltage mode devices that meet or exceed the requirements of industry standards ANSI RS-485 and ISO 8482:1987(E).
●FEATURES
●• Designed for High-Speed Multipoint Data Transmission Over Long Cables
●• Operate With Pulse Durations as Low as 30 ns
●• Low Supply Current . . . 5 mA Max
●• Meet or Exceed the Requirements of ANSI Standard RS-485 and ISO 8482:1987(E)
●• 3-State Outputs for Party-Line Buses
●• Common-Mode Voltage Range of –7 V to 12 V
●• Thermal Shutdown Protection Prevents Driver Damage From Bus Contention
●• Positive and Negative Output Current Limiting
●• Pin Compatible With the SN75ALS180
