Overview
The SN75ALS162DWR is an eight-channel general-purpose interface bus (GPIB) transceiver produced by Texas Instruments. This monolithic device is designed using high-speed, advanced low-power Schottky process technology to manage and transfer data between operating units of a multiple-controller instrumentation system. It is particularly useful in systems that require compliance with the IEEE Standard 488-1978 (GPIB). When combined with the SN75ALS160 octal bus transceiver, the SN75ALS162DWR provides a complete 16-wire interface for the IEEE 488 bus.
