Working Principles

The SN74LVC373ADBR is a transparent latch that stores and outputs 8 bits of data. It operates by latching the input data when the latch enable (LE) signal is high. The stored data remains unchanged as long as the LE signal is high. When the LE signal goes low, the output data follows the input data.

The output enable (OE) signal controls the output state. When OE is high, the outputs are in a high-impedance state, allowing external devices to drive the bus. When OE is low, the outputs reflect the stored data.

The SN74LVC373ADBR is widely used in various digital systems where data storage and retrieval are required. Some common application fields include:

1. Microcontrollers and microprocessors
2. Data communication systems
