FACT DATA
The MC74AC373/74ACT373 consists of eight latches with 3-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.
Eight Latches in a Single Package
