HEF4738V
Description
The inputs IRFD, IDAC, IDAV, IIFC, IREN, IATN, IIDY and IDIO1 to IDIO7 must be connected via an inverting TTL to LOCMOS level converter to the respective bus lines: NRFD, NDAC, DAV, IFC, REN, ATN, IDY and DIO1 to DIO7. The outputs ORFD, ODAC, ODAV and OSRQ can drive one standard TTL load and are suitable for driving NRFD, NDAC, DAV and SRQ via an inverting bus-driver circuit.
