Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the complete ordering part number against official Texas Instruments documentation to ensure correct suffixes for packaging and tape-and-reel specifications. Confirm RoHS compliance status and lead-free manufacturing details directly from the manufacturer's datasheet or authorized distributor catalogs prior to procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel, non-inverting buffer with three-state control is required for 1.65-V to 5.5-V systems. Consider its 5.5-V tolerant inputs for interfacing between different voltage domains. Evaluate the SOT-23-5 package constraints for space-limited designs and verify that the propagation delay meets system timing requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

Buffers, Drivers, Receivers, Transceivers FAQ

Does the device support partial-power-down mode?

Yes, the Ioff circuitry 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 accept voltages up to 5.5 V, allowing operation with 5-V VCC supplies even if the device itself operates at lower voltages.
