This circuit provides compatibility with the IEEE-488 bus for low volume or one of a kind test instruments. See Institute of Electrical and Electronic Engineers (IEEE) Standard 488-1975/ANSI MC1.1-1975 for a description of the bus. The circuit enables the test instrument to assume a noncontroller role in the bus and the capability of being able to be set up as a bus listener or talker. This approach uses conventional MSI (medium scale integration) circuits versus a microprocessor or an LSI (large scale integration) approach. It also features a two-wire handshake for input/output of data to and from a test instrument.
