Functional Description

The LVX373 contains eight D-type latches with TRI-STATE

standard outputs When the Latch Enable (LE) input is

dition the latches are transparent ie

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 tran-

sition of LE The TRI-STATE standard outputs are con-

trolled by the Output Enable (OE) input When OE is LOW

the standard outputs are in the 2-state mode When OE is

HIGH the standard outputs are in the high impedance mode

but this does not interfere with entering new data into the

latches
