The IN74AC652 is identical in pinout to the LS/ALS652, HC/HCT652. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS 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.
The IN74AC652 has noninverted outputs.
