DESCRIPTION

The HEF4738V is an implementation of the IEC-bus as described in IEC report 66 CO 22 (interface system for programmable measuring apparatus) as well as in IEEE standard 488-1975 (standard digital interface for programmable instrumentation).

Together with bus-drivers, level converters and multiplexers it is suitable for connecting electronic programmable and non-programmable equipment to an IEC/IEEE interface bus.

All inputs have standard HE4000B family levels. In the circuit the following standard interface functions are incorporated:

? Complete source handshake (subset SH1)

? Complete acceptor handshake (subset AH1)

? Basic talker with serial poll and talk-only mode (when It = LOW, subset T1; It = HIGH, subset T5)

? Basic listener with listen-only mode (when It = LOW, subset L1; It = HIGH, subset L3)

? Complete service request (subset SR1)

? Complete remote local (subset RL1)

? Remote parallel poll configuration (subset PP1)

? Complete device clear (subset DC1)

? Complete device trigger (subset DT1)

? Some controller facilities
