Functional Description

The PC74HC373P consists of eight D-type latches with 3-state outputs that can be used as bus drivers. The device features a common Latch Enable (LE) input and a common Output Enable (OE) input. When LE is high, the flip-flops on the '373' take the data from the D inputs and hold it. When OE is low, the outputs are active and reflect the data that has been latched. If OE is high, the outputs go to a high-impedance state, effectively disconnecting the latch from the bus.

Applications

With its ability to interface with the bus-structured systems, the NXP PC74HC373P is suitable for a variety of applications, including:

• Buffer storage
• Memory address latching
• Data storage and transfer
• Control systems
• Bus transceiver with 3-state outputs
