• Single supply voltage: It operates within a specific voltage range, limiting compatibility with systems requiring different voltage levels.

Working Principles

SN74ABT373DBR functions as an octal transparent latch. When the enable input (G) is active, the latch allows the data inputs (D0-D7) to pass through to the corresponding outputs (Q0-Q7). When the enable input is inactive, the outputs retain their previous states.

Detailed Application Field Plans

SN74ABT373DBR finds applications in various fields, including:

1. Microcontrollers: It can be used to interface with external devices and store data.
2. Data storage systems: The latch enables efficient data transfer and control within storage systems.
3. Communication systems: SN74ABT373DBR facilitates data buffering and synchronization in communication protocols.
