Latches Procurement Notes

Verify the specific package type and tape-and-reel quantity against the official TI orderable addendum. Confirm that the E4 suffix corresponds to the required lead finish and environmental compliance standards for your manufacturing process. Ensure the operating temperature range matches your system requirements.

Latches Selection Notes

Select this component when designing systems requiring octal data latching with high-speed performance and 3-state bus control. It is suitable for applications needing voltage translation between 5-V logic inputs and lower voltage cores. Consider its drive strength and parasitic capacitance characteristics for high-frequency signal integrity.

Latches Part Context

This part belongs to the SN74LVC573A family of octal transparent D-type latches. It shares functional similarities with other LVC series devices but is optimized for low-voltage operation. The PW package variant offers a compact surface-mount solution for space-constrained designs.

Latches FAQ

How does the Ioff feature benefit the SN74LVC573APWE4?

The Ioff feature disables the outputs when the device is powered down, preventing damaging current backflow through the device.

What is the maximum input voltage tolerance?

The inputs can accept voltages up to 5.5 V, allowing for mixed-mode signal operation with 5-V interfaces while using a lower VCC.
