74F649 Overview
The 74F647 and 74F649 Transceivers/Registers consist of bus transceiver circuits with open-collector outputs, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or from the internal registers. Data on the A or B bus will be clocked into the registers as the appropriate clock pin goes to a High logic level. Output Enable (OE) and DIR pins are provided to...
