SN75LBC170 に関する概要
The SN65LBC170 and SN75LBC170 are monolithic integrated circuits designed for bidirectional data communication on multipoint bus-transmission lines. 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 driver’s active-high enable and the receiver’s active-low enable are tied together internally and provide a direction input for each driver/receiver pair.
The SN75LBC170 is characterized for operation over the temperature range of 0°C to 70°C. The SN65LBC170 is characterized for operation over the temperature range of –40°C to 85°C.
