74AHC3G14GT,115

Overview

The Nexperia 74AHC3G14GT,115 is a triple inverting Schmitt trigger IC housed in an 8-terminal XSON package (SOT833-1). It operates within a supply voltage range of 2.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features overvoltage tolerant inputs up to 5.5 V, ensuring compatibility in mixed-voltage environments. Static characteristics include a maximum input leakage current of 2.0 μA at -40 °C to +125 °C and a maximum supply current of 40 μA under specified conditions.

Feature Summary

• Triple inverting buffers with Schmitt-trigger inputs for noise immunity
• Overvoltage tolerant inputs allowing use as translators in mixed voltage systems
• Symmetrical output impedance and balanced propagation delays

Applications

• Wave and pulse shaping in highly noisy environments
• Astable multivibrator circuits
• Monostable multivibrator circuits

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select this component when designing logic interfaces requiring signal conditioning in electrically noisy environments. The Schmitt trigger action ensures clean output transitions from slowly changing or distorted input signals. Ensure the design accommodates the 5.5 V input tolerance if interfacing with higher voltage logic levels while operating at lower supply voltages.

Part Context

This part belongs to the Nexperia 74AHC family of high-speed CMOS logic devices. The 'GT' suffix specifically denotes the XSON8 plastic extremely thin small outline package (SOT833-1), which measures 1 mm x 1.95 mm x 0.5 mm. This packaging option provides a compact footprint suitable for space-constrained surface-mount applications compared to traditional leaded packages.

Replacement Considerations

The 74AHCT3G14GT,115 serves as a functional substitute within the same package, differing primarily in input threshold levels compatible with TTL logic rather than standard CMOS levels.
