The Intel'" 8293 GPIB Transceiver is a high current, non-inverting buffer chip designed
to
interface
the.
8291
GPIB
Talker/Listener
or
the 6292 GPIB Controller with the
8291
to
the
I.EEE
Standard 488-1978 Instrumentation Interface
Bus. Each GPIB interface would contain two 8293 Bus Transceivers. In addition, the 8293 can also be used as a general
purpose bus driver.
