Overview

SL74HC651 Octal 3-State Bus Transceivers and D Flip-Flops High-Performance Silicon-Gate CMOS The SL74HC651 is identical in pinout to the LS/ALS651.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs.
These devices consists of bus transceiver circuits, D-type flip-flop, and control circuitry arranged for multiplex transmission of data directly from the data bus or from the internal storage registers.
Direction and Output Enable are provided to select the read-time or stored data function.
Data on the A or B Data bus, or both, can be stored in the internal D flip-flops by low-to-high transitions at the appropriate clock pins (A-to-B Clock or B-to-A Clock) regardless of the select or enable or enable control pins.
When A-to-B Source and B-toA Source are in the real-time transfer mode, it is als o possible to store data without using the internal D-type flip-flops by simulta-neously enabling Direction and Output E...
