SN74AUC1G17DBVR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC1G17DBVR is a single Schmitt-trigger buffer from the Texas Instruments AUC logic family, housed in a 5-pin SOT-23 package. It operates within a supply voltage range of 0.8 V to 2.7 V and features non-inverting Boolean logic (Y = A). The device provides push-pull outputs with ±9 mA drive capability at 2.3 V and maintains a maximum static current of 10 µA. Designed for mixed-mode signal environments, it supports 3.6-V I/O tolerance while operating at lower voltages.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Schmitt-trigger action provides distinct input threshold levels for positive-going and negative-going signals to ensure noise immunity.
• Ioff circuitry enables partial power-down mode by disabling outputs to prevent damaging backflow currents when the device is unpowered.
• Inputs are tolerant up to 3.6 V, allowing safe operation in mixed-mode systems where the device supply voltage is lower than the driving signal level.

Buffers, Drivers, Receivers, Transceivers Applications

• Portable audio devices such as MP3 players and recorders
• Solid-state drives for client and enterprise storage
• Wireless peripherals including headsets, keyboards, and mice

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DBVR' corresponds to the SOT-23 package and tape-and-reel carrier configuration. Confirm that the RoHS status and lead finish match project requirements. Ensure the active production status is validated against the latest Texas Instruments product folder before finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel buffer with hysteresis is required for sub-1-V or low-voltage digital applications. The AUC series offers high speed and low power consumption compared to legacy families. Verify that the 3.6-V input tolerance meets the interface requirements of the connected source signals.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments SN74AUC1Gxx Little Logic series, designed for ultra-low voltage and high-speed performance. The AUC family utilizes advanced semiconductor technology to achieve propagation delays under 5 ns while minimizing power dissipation. It serves as a compact solution for space-constrained portable electronics.
