74FR573
Octal D-Type Latch with 3-STATE Outputs
General Description
The 74FR573 is a high speed octal latch with buffered
common Latch Enable (LE) and buffered common Output
Enable (OE) inputs.
This device is functionally identical to the 74F573.
Features
s Broadside pinout aids in PC layout
s Functionally identical to the 74F373, 74F573
s Outputs have current sourcing capability of 15 mA and
current sinking capability of 64 mA
s Guaranteed pin-to-pin skew

Functional Description
The 74FR573 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 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.
