Latches Procurement Notes

Verify the manufacturer designation as Integrated Device Technology Inc or Texas Instruments depending on corporate history records. Confirm the SOIC-20 package type and non-inverting polarity match system requirements. Ensure the operating temperature range covers the intended environmental conditions. Cross-reference datasheet revisions to confirm pinout compatibility with existing layouts.

Latches Selection Notes

Select this component when an octal latch with high-speed transparency is required. The 4.7 ns delay suits applications needing rapid data capture without significant timing penalties. The 32 mA drive strength allows direct interfacing with moderate capacitive loads. Verify that the 5 V nominal supply aligns with the system power rails before integration.

Latches Part Context

This part belongs to the FCT573T family of octal transparent latches. These devices are designed for high-performance digital applications requiring reliable data retention and fast transition times.
