Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type and marking code against the datasheet ordering information to ensure correct identification. Confirm RoHS compliance and environmental category requirements match project specifications. Check for any lead-free soldering process compatibility if high-temperature assembly is required. Ensure all unused inputs are tied to VCC or GND during operation to maintain proper device function.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits that require buffering between 5-V logic and 3.3-V systems. The SN74LVT240ADGVR is suitable for applications needing hot-swap capabilities due to its integrated Ioff circuitry. Consider the TVSOP-20 package for space-constrained designs requiring surface-mount technology. Verify supply voltage ranges align with the 2.7-V to 3.6-V recommended operating conditions.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle hot-insertion?

The SN74LVT240ADGVR includes Ioff circuitry that disables outputs when powered down to prevent backflow, and power-up 3-state circuitry that places outputs in a high-impedance state during power transitions to avoid driver conflicts.

What is the input voltage tolerance?

The device supports mixed-mode signal operation, allowing 5-V input and output voltages even when the supply voltage (VCC) is set to 3.3 V.
