OCTAL

TRANSCEIVER/REGISTER

WITH 3-STATE OUTPUTS

(NON-INVERTING)

The MC74AC646/74ACT646 consist of registered bus transceiver circuits,

with outputs, D-type flip-flops and control circuitry providing multiplexed transmission

of data directly from the input bus or from the internal storage registers. Data on the

A or B bus will be loaded into the respective registers on the LOW-to-HIGH transition

of the appropriate clock pin (CAB or CBA). The four fundamental data handling

functions available are illustrated in the following figures.
