FACT DATA
FUNCTIONAL DESCRIPTION
The MC74AC573/74ACT574 contains eight D-type latches
with 3-state 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 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 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.
