FUNCTIONAL DESCRIPTION
The MC74AC573/74ACT574 contains eight Dtype
latches with 3state output buffers. When the Latch Enable
(LE) input is HIGH, data on the Dn 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 a setup time preceding the HIGHtoLOW
transition of LE. The 3state buffers are controlled by the
Output Enable (OE) input. When OE is LOW, the buffers are
enabled. When OE is HIGH the buffers are in the high
impedance mode but this does not interfere with entering
new data into the latches.
