Description

This family of high-speed-Schottky 8-channel bi-directional transceivers DS75161A is designed to interface TTL/MOS logic to the IEEE Standard 488-1978 General Purpose Interface Bus (GPIB).PNP inputs are used at all driver inputs for minimum loading,and hysteresis is provided at all receiver inputs for added noise margin.The IEEE-488 required bus termination is provided internally with an active turn-off feature which dis-connects the termination from the bus when V_CC is removed. The General Purpose Interface Bus is comprised of 16 sig-nallines-8 for data and 8 for interface management.The data lines are always implemented with DS75160A,and the management lines are either implemented with DS75161A in a single-controller system.
