Overview
SL74HC652 Octal 3-State Bus Transceivers and D Flip-Flops High-Performance Silicon-Gate CMOS The SL74HC652 is identical in pinout to the LS/ALS652.
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 also possible to store data without using the internal D-type flip-flops by simulta-neously enabling Direction and Output Enable.
In this configuration each output reinforces its input.
Thus, when all other data sources to the two sets of bus lines are at high impedance, each set of bus lines will remain at its last state.
The SL74HC652 has noninverted outputs.
