SN74AUC1G14YZPR

Overview

The SN74AUC1G14YZPR is a single Schmitt-trigger inverter from the Texas Instruments AUC logic family, housed in a 5-pin DSBGA 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 a maximum propagation delay of 2.5 ns at 1.8 V and includes dedicated Ioff circuitry for partial-power-down applications. It provides robust ESD protection exceeding 2000 V via the human-body model.

Feature Summary

• Schmitt-trigger action provides distinct input threshold levels for positive-going and negative-going signals to prevent noise-induced switching.
• Ioff circuitry disables outputs to prevent damaging current backflow when the device is powered down.
• NanoFree™ packaging utilizes the die as the package for minimal footprint.
• High latch-up performance exceeds JESD 78 Class II standards.

Applications

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

Procurement Notes

Verify component status before procurement as the SN74AUC1G14YZPR is listed as obsolete in official documentation. Confirm availability through direct manufacturer channels or authorized distributors. Ensure design updates account for potential discontinuation risks associated with this specific package variant.

Selection Notes

Select this component for designs requiring sub-1-V operation and mixed-mode signal compatibility. The NanoFree™ package is suitable for space-constrained portable electronics. Verify that the required propagation delay and output drive capabilities align with system timing constraints under the intended operating voltage conditions.

Part Context

This part belongs to the SN74AUC1G series of Little Logic devices designed for low-voltage applications. The YZP suffix denotes the 5-pin DSBGA (NanoFree™) package configuration. It is part of the broader AUC logic family optimized for high-speed, low-power digital signal processing in consumer and industrial electronics.

Replacement Considerations

Consult the TI Package Option Addendum for qualified alternative packages such as DBVR or DCKR. Verify functional equivalence regarding pinout and electrical characteristics when transitioning between different package types within the same logic family.
