Functional Description
The ’AC’ACT843 consists of nine D-type latches with
TRI-STATE outputs The flip-flops appear transparent to the
data when Latch Enable (LE) is HIGH This allows asyn-
chronous operation as the output transition follows the data
in transition On the LE HIGH-to-LOW transition the data
that meets the setup times is latched Data appears on the
bus when the Output Enable (OE) is LOW When OE is
HIGH the bus output is in the high impedance state In
addition to the LE and OE pins the ’AC’ACT843 has a
Clear (CLR) pin and a Preset (PRE) pin These pins are ideal
for parity bus interfacing in high performance systems
When CLR is LOW the outputs are LOW if OE is LOW
When CLR is HIGH data can be entered into the latch
When PRE is LOW the outputs are HIGH if OE is LOW
Preset overrides CLR
