MC74HC646, Octal 3-State Bus Transeceivers and D Flip-Flops

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
