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.
