Latches Procurement Notes

Verify the specific suffix 'DB' corresponds to the SSOP-20 package configuration, as other suffixes indicate different form factors. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments. Ensure the design accommodates the specified 4.5V to 5.5V operating voltage range and thermal requirements for the intended application environment.

Latches Selection Notes

Select this component when an octal latch with tri-state outputs is required for 5V logic systems. The SN74LV373A series supports mixed-mode voltage operations, allowing inputs and outputs to interface with varying voltage levels. Verify that the SSOP-20 package fits the PCB layout constraints and that the 16mA drive current meets the load requirements of the connected circuitry.

Latches Part Context

This part belongs to the SN74LV373A family of octal transparent D-type latches designed for 2V to 5.5V operation. These devices are engineered for high-speed data storage and bus driving applications. The LV series offers improved performance over standard TTL while maintaining compatibility with various logic families used in industrial and consumer electronics.
