Working Principles

The SN74ABT16373ADL is a latch-based integrated circuit that stores and transfers data. It consists of 16 individual D-type latches, each capable of storing one bit of information. The latch enable inputs control when the data is stored, while the clock inputs determine when the stored data is transferred to the outputs.

When the latch enable input is active, the data at the corresponding data input is latched and stored. The stored data remains unchanged until a new value is latched. The clock input synchronizes the transfer of the stored data to the outputs, ensuring accurate timing.

The output enable inputs allow the outputs to be disabled, effectively disconnecting them from the rest of the circuit. This feature is useful when multiple devices are connected together, and only one device should be driving the bus at a time.

Detailed Application Field Plans

The SN74ABT16373ADL is commonly used in various applications, including:

1. Data communication systems: Used for data storage and transfer in high-speed communication protocols such as Ethernet.
2. Memory modules: Integrated into memory modules to store and retrieve data efficiently.
3. Microprocessor systems: Employed in microprocessor-based systems to handle data transfer between different components.
4. Industrial automation: Utilized in industrial control systems for reliable data storage and transmission.
5. Automotive electronics: Incorporated into automotive electronic systems for data processing and communication.
