Functional Description
The ABT373 contains eight D-type latches with 3-STATE
output buffers. When the Latch Enable (LE) input is HIGH,
data on the D
n
inputs 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 at setup time preceding the HIGH-to-LOW transition
of LE. The 3-STATE buffers are controlled by the Output
Enable (OE) input. When OE is LOW, the buffers are in the
bi-state mode. When OE is HIGH the buffers are in the high
impedance mode but this does not interfere with entering
new data into the latches.
