74LVT373PW,118

The 74LVT373PW is an octal BiCMOS transparent D Latch designed for VCC operation at 3.3V. This device coupled to eight 3-state output buffers. The two sections of the device are controlled independently by LE and OE\ control gates. The data on the Dn inputs are transferred to the latch outputs when the LE input is high. The latch remains transparent to the data inputs while LE is high and stores the data that is present one setup time before the high-to-low enable transition. The 3-state output buffers are designed to drive heavily loaded 3-state buses, MOS memories or MOS microprocessors. The active-low OE controls all eight 3-state buffers independent of the latch operation. When OE\ is low, the latched or transparent data appears at the outputs. When OE\ is high, the outputs are in the high-impedance OFF-state, which means they will neither drive nor load the bus.
