to the device may occur. The databook specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. National does not recommend operation of FACT® circuits outside databook specifications.

The 54AC373 consists of eight latches with TRI-STATE outputs for bus organized system applications. The flip-flops 54AC373 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.
