Functional Description

Outputs

The ’FCT573 contains eight D-type latches with TRI-STATE

output buffers. When the Latch Enable (LE) input is HIGH,

data on the D_ninputs 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

TRI-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.
