Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PW' confirms the TSSOP-20 package variant rather than tape-and-reel options. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure input voltage limits do not exceed 5.5 V to maintain device integrity and latch-up protection standards.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring 8-channel buffering with 3-state control in low-voltage environments. The LVC series offers a balance of speed and power efficiency suitable for portable applications. Verify that the TSSOP-20 footprint aligns with PCB layout constraints and thermal requirements for the target operating temperature range.

Buffers, Drivers, Receivers, Transceivers Part Context

Buffers, Drivers, Receivers, Transceivers FAQ

What is the maximum input voltage supported by this device?

The device accepts input voltages up to 5.5 V, enabling compatibility with 5V logic systems while operating on lower supply voltages.

How does the Ioff feature benefit system design?

Ioff ensures outputs remain in a high-impedance state during power-off conditions, preventing back-driving and protecting downstream components during hot-swap scenarios.
