• Propagation delay of 3.8ns may introduce timing constraints in certain designs.
• ±24mA output current may not be sufficient for driving high-current loads.

Working Principles

The SN74ABT373PWE4 operates as an octal transparent D-type latch with 3-state outputs. When the Output Enable (OE) input is high, the latch is transparent, allowing the data inputs (D0-D7) to pass through to the corresponding outputs (Q0-Q7). When OE is low, the outputs are in a high-impedance state, effectively disconnecting them from the bus.

The latch is controlled by the Clock Pulse (CP) input. On the rising edge of the clock signal, the data present at the inputs is latched and stored. The stored data remains unchanged until the next rising edge of the clock pulse.

Detailed Application Field Plans

The SN74ABT373PWE4 can be used in various applications that require data storage and transfer, such as:

1. Microprocessors and microcontrollers
2. Data communication systems
3. Memory modules
4. Digital signal processing
5. Industrial automation
