Overview
MOTOROLA
SEMICONDUCTOR TECHNICAL DATA
Octal 3-State Bus Transceivers and D Flip-Flops
High–Performance Silicon–Gate CMOS
The MC54/74HC646 is identical in pinout to the LS646.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
These devices are bus transceivers with D flip–flops.
Depending on the status of the Data–Source Selection pins, data may be routed to the outputs either from the flip–flops or transmitted real–time from the inputs (see Function Table and Application Information).
The Output Enable and the Direction pins control the transceiver’s function.
Bus A and Bus B cannot be routed as outputs to each other...
