Potential applications include serial or parallel data transmission, cabled peripheral buses with twin axial, ribbon, or twisted-pair cabling. These devices are suitable for FAST–20 SCSI and can transmit or receive data pulses as short as 25 ns, with skew less than 3 ns. These devices combine three 3-state differential line drivers and three differential input line receivers, all of which operate from a single 5-V power supply. The driver differential outputs and the receiver differential inputs are connected internally to form three differential input/output (I/O) bus ports that are designed to offer minimum loading to the bus whenever the driver is disabled or VCC = 0. These ports feature a wide common-mode voltage range making the device suitable for party-line applications over long cable runs. The SN75LBC171 is characterized for operation over the temperature range of 0 °C to 70°C. The SN65LBC171 is characterized for operation over the temperature range of –40 °C to 85°C.
