Overview
The SN75162BDWR is an octal general-purpose interface bus transceiver produced by Texas Instruments. It is designed to meet the requirements of IEEE Standard 488-1978 (GPIB) and is part of a family of high-speed, low-power Schottky devices. This component is particularly useful in instrumentation systems that require multiple controllers, providing the necessary bus-management and data-transfer signals between operating units. The SN75162BDWR features eight driver-receiver pairs, enabling bidirectional communication and supporting both single and multiple-controller configurations.
