Functional Description
The ACT533 contains eight D-type latches with 3-STATE
standard outputs. When the Latch Enable (LE) input is
HIGH, data on the D
n
inputs enters the latches. In this con-
dition 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 at setup time preceding the HIGH-to-LOW
transition of LE. The 3-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.
