SN74AUC1G126YEPR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC1G126YEPR is a single bus buffer gate with tri-state output from Texas Instruments, operating at VCC voltages between 0.8 V and 2.7 V. It features overvoltage-tolerant inputs up to 3.6 V, supporting mixed-mode signal operation. The device includes Ioff circuitry for partial power-down applications, preventing backflow current when powered down. It offers low power consumption with a maximum ICC of 10 µA and supports high-speed data transmission with a maximum propagation delay of 2.5 ns at 1.8 V.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type matches the design requirements, as the YZP NanoFree package differs in dimensions from standard SC70 or SOT-23 variants. Confirm the ordering suffix aligns with the desired reel quantity and lead-free status. Ensure the component meets RoHS compliance standards required by the target assembly process.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring a single-channel buffer with independent output enable control. It is suitable for mixed-voltage systems due to its 3.6-V input tolerance while operating on lower supply rails. Consider the NanoFree package size constraints and thermal characteristics when choosing this part over larger footprint alternatives.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74AUC1G series of ultra-low-power logic gates. It is designed specifically for 1.65-V to 1.95-V operation but remains functional across a broader range. The family emphasizes miniaturization through NanoFree packaging and low standby current for battery-powered portable electronics.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle partial power-down conditions?

The Ioff circuitry automatically disables the outputs when the supply voltage drops to 0 V, preventing damaging current backflow through the device.

What is the function of the OE pin?

The Output Enable (OE) pin controls the state of the output. When OE is low, the output enters a high-impedance state; when high, the output follows the input A.
