SN74AUC1G14YZAR

Overview

The SN74AUC1G14YZAR is a single Schmitt-trigger inverter from the Texas Instruments AUC logic family, housed in a NanoFree DSBGA-5 package. It operates within a supply voltage range of 0.8 V to 2.7 V and supports mixed-mode signal operation with 3.6-V I/O tolerance. The device features sub-1-V operability, low power consumption with a maximum ICC of 10 µA, and an output drive capability of ±8 mA at 1.8 V. Propagation delay (tpd) reaches a maximum of 2.5 ns at 1.8 V with a 30 pF load.

Feature Summary

• Schmitt-trigger action provides distinct positive-going and negative-going input threshold levels for noise immunity.
• Ioff circuitry enables partial-power-down mode by disabling outputs to prevent damaging backflow current.
• ESD protection exceeds JESD 22 standards, including 2000-V human-body model and 1000-V charged-device model ratings.

Applications

• Partial-power-down applications requiring controlled output disablement
• Mixed-mode signal processing circuits
• Signal conditioning for noisy environments

Procurement Notes

Verify the specific ordering suffix 'YZAR' corresponds to the NanoFree DSBGA-5 package with tape and reel packaging. Confirm that the component meets RoHS requirements as indicated in manufacturer documentation. Ensure design compatibility with the specified operating temperature range of -40°C to 85°C.

Selection Notes

Select this component when a single inverter with hysteresis is required for low-voltage digital logic applications. The AUC series is optimized for 1.8-V operation but remains functional down to 0.8 V. Consider the small form factor of the DSBGA package for space-constrained designs.

Part Context

This device belongs to the Texas Instruments AUC Little Logic family, designed for high-speed, low-power applications. The AUC series utilizes advanced CMOS technology to achieve performance comparable to faster logic families while maintaining significantly lower power consumption suitable for portable and battery-operated systems.

FAQ

What is the function of the Ioff feature?

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

How does the Schmitt trigger improve performance?

It provides different input threshold levels for positive-going (VT+) and negative-going (VT-) signals, offering improved noise immunity compared to standard inverters.
