IN74HC652A
TECHNICAL DATA
Octal 3-State Bus Transceivers and D Flip-Flops
High-Performance Silicon-Gate CMOS
The IN74HC652A is identical in pinout to the LS/ALS652. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible with LS/ALSTTL outputs. These devices consist 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-to-A Source are in the real-time transfer mode, it is also possible to store data without using the internal D-type flip-flops by simulta-neously enabling Direction...
