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
