54AC373

General Description

The ’AC/’ACT373 consists of eight latches with TRI-STATE

outputs for bus organized system applications. The flip-flops

appear transparent to the data when Latch Enable (LE) is

HIGH. When LE is LOW, the data that meets the setup time

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.
