DS75160A/DS75161A
IEEE-488 GPIB Transceivers
General Description
This family of high-speed-Schottky 8-channel bi-directional
transceivers 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 VCC is removed.
The General Purpose Interface Bus is comprised of 16 sig-
nal lines — 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.
