MC74F543 OCTAL REGISTERED TRANSCEIVER, NON-INVERTING, 3-STATE
MC74F543 Octal Registered Transceivers contain sets data flowing either direction. Separate Latch Enable (LEAB, LEBA) Enable (OEAB, OEBA) inputs provided each register permit independent control inputting outputting either direction data flow. MC74F543 noninverting data path. outputs guaranteed sink while outputs rated

FUNCTIONAL DESCRIPTION MC74F543 contains sets eight D-type latches, with separate input controls each set. data flow from example, A-to-B Enable (EAB) Input must order enter data from take data from indicated Function Table. With LOW, signal A-to-B Latch Enable (LEAB) input makes A-to-B latches transparent; subsequent LOW-to-HIGH
transition LEAB signal puts latches storage mode their outputs longer change with inputs. With OEAB both LOW, 3-State output buffers active reflects data present output latches. Control data flow from similar, using EBA, LEBA, OEBA inputs.
