Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type (TSSOP, TVSOP, or VFBGA) required for your design, as the base part number covers multiple physical configurations. Confirm that the Z suffix corresponds to the intended VFBGA variant if applicable. Ensure compatibility with the -40°C to +85°C operating temperature range. Check for RoHS compliance status on the latest ordering information before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring low-voltage operation down to 0.8 V with mixed-mode signal support. It is suitable for applications needing high-density bus driving with inverting logic. Consider the Ioff feature if partial-power-down functionality is necessary to prevent backflow currents during power cycles.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the Ioff feature benefit the SN74AUC16240ZQLR?

The Ioff circuitry disables the outputs when the device is powered down, preventing damaging current backflow through the device during partial-power-down applications.

What is the input voltage tolerance of this buffer?

The device is designed specifically for 1.8-V operation but features 3.6-V I/O tolerance, allowing it to support mixed-mode signal operations safely.
