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.
