Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package suffix against the manufacturer's latest datasheet to ensure correct pinout and thermal characteristics. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to assembly. Ensure ordering quantities align with standard reel sizes if applicable. Cross-reference the part number with official distributor catalogs to validate current availability and lead times.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring a single-channel non-inverting buffer with high-speed performance and wide voltage tolerance. The 3.7 ns propagation delay at 3.3 V makes it suitable for moderate-speed digital interfaces. Consider the NanoStar or NanoFree package options for space-constrained PCB layouts. Verify input voltage levels do not exceed the 5.5 V absolute maximum rating under all operating conditions.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the Ioff feature benefit system design?

The Ioff circuitry disables outputs when the device is powered down, preventing damaging current backflow through the device. This supports partial-power-down mode operations and protects downstream components.

What is the maximum input voltage supported by this buffer?

The inputs accept voltages up to 5.5 V, allowing compatibility with 5-V logic systems even when the device is operated at lower supply voltages within its 1.65 V to 5.5 V range.
