MC74AC646, MC74ACT646

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 Figures

1 to 4.
