MC74AC573, MC74ACT573
Octal Buffer/Line Driver
with 3-State Outputs
The MC74AC573/74ACT573 is a high–speed octal latch with
buffered common Latch Enable (LE) and buffered common Output
Enable (OE) inputs.
The MC74AC573/74ACT573 is functionally identical to the
MC74AC373/74ACT373 but has inputs and outputs on opposite sides.

FUNCTIONAL DESCRIPTION
TRUTH TABLE
The MC74AC573/74ACT574 contains eight D–type
latches with 3–state output buffers. When the Latch Enable
Inputs
Outputs
OE
LE
D
O
n
n
(LE) input is HIGH, data on the D inputs enters the latches.
n
L
L
L
H
H
L

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.
