Functional Description

Truth Table

The ’ACQ/’ACTQ373 contains eight D-type latches with

TRI-STATE standard outputs. When the Latch Enable (LE)

input is HIGH, data on the D_ninputs enters the latches. In

this condition the latches are transparent, i.e., a latch output

will change state each time its D input changes. When LE is

LOW, the latches store the information that was present on

the D inputs a setup time preceding the HIGH-to-LOW tran-

sition of LE. The TRI-STATE standard outputs are controlled

by the Output Enable (OE) input. When OE is LOW, the stan-

dard outputs are in the 2-state mode. When OE is HIGH, the

standard outputs are in the high impedance mode but this

does not interfere with entering new data into the latches.
