SN74AUP3G14RSER

Overview

The SN74AUP3G14RSER is a low-power triple Schmitt-trigger inverter from Texas Instruments, part of the AUP logic series. It operates within a supply voltage range of 0.8 V to 3.6 V and features I/O tolerance up to 3.6 V for mixed-mode system applications. The device is housed in an 8-pin UQFN package (RSE) with dimensions of 1.5 mm by 1.5 mm. Key electrical parameters include a maximum static current of 900 nA and a propagation delay of 6.2 ns at 3.3 V with a 30 pF load. It supports a wide operating temperature range from -40°C to +85°C.

Feature Summary

• Triple Schmitt-trigger inputs provide noise filtering and hysteresis for clean signal transitions.
• Low static power consumption minimizes energy usage during standby or idle states.
• 3.6-V I/O tolerance enables direct interfacing between different voltage domains in mixed-signal systems.

Applications

• Mixed-mode signal processing circuits requiring level shifting
• Clock buffering and waveform shaping in low-power embedded systems
• Noise-immune input conditioning for digital control lines

Procurement Notes

Verify the specific suffix RSER corresponds to the UQFN-8 (1.5x1.5 mm) package configuration. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering part number matches the required tape-and-reel quantity specifications provided in the datasheet. Cross-reference the manufacturer date code to verify production batch authenticity.

Selection Notes

Select this component when Schmitt-trigger action is required for noisy environments alongside ultra-low power constraints. The 0.8 V minimum supply voltage allows operation in battery-powered devices where voltage drops significantly. Compare propagation delay characteristics against standard non-Schmitt inverters if signal integrity timing margins are critical for the target application frequency.

Part Context

This device belongs to the SN74AUP3Gxx family of single-function gates optimized for portable and battery-operated electronics. The AUP series utilizes advanced CMOS technology to achieve performance levels comparable to faster logic families while maintaining significantly lower power dissipation. The RSE suffix specifically denotes the small outline quad flat no-lead variant suitable for space-constrained printed circuit board layouts.

Replacement Considerations

SN74AUP3G04RSER serves as a functional substitute but lacks Schmitt-trigger inputs, offering only standard inversion without hysteresis. Designers must evaluate whether the noise immunity provided by the Schmitt trigger is necessary for the specific signal path before substituting.
