Functional Description
The MC74AC573/74ACT574 contains eight D−type
latches with 3−state output buffers. When the Latch Enable
O
n
(LE) input is HIGH, data on the D
inputs enters the latches.
n
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
0
on the D inputs a setup time preceding the HIGH−to−LOW
transition of LE. The 3−state buffers are controlled by the
Output Enable (OE
enabled. When OE
) input. When OE is LOW, the buffers are
is HIGH the buffers are in the high
impedance mode but this does not interfere with entering
new data into the latches.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously . If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
