74AHCT3G14DC,125

Overview

The Nexperia 74AHCT3G14DC,125 is a triple inverting Schmitt trigger implemented in CMOS technology. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL input switching levels. The device provides three independent inverters with Schmitt-trigger inputs for high noise immunity. It is housed in an 8-lead VSSOP plastic package (SOT765-1) and supports an ambient temperature range from -40 °C to +125 °C.

Feature Summary

• Schmitt-trigger inputs convert slowly changing signals into sharply defined output transitions
• Overvoltage tolerant inputs allow operation in mixed voltage environments up to 5.5 V
• Symmetrical output impedance ensures balanced propagation delays

Applications

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

Selection Notes

Select this component when TTL logic compatibility is required alongside Schmitt-trigger noise filtering. The AHCT series differs from AHC by utilizing TTL input thresholds rather than CMOS levels. Ensure the design accommodates the minimum 4.5 V supply requirement and verify that the VSSOP8 thermal dissipation characteristics meet the application's power constraints.

Part Context

This part belongs to the Nexperia 74AHC/AHCT 3G family of single-pole double-throw switches and logic gates. These devices are designed for low-power applications requiring small form factors. The 3G designation indicates three functional circuits within a single compact package, optimizing board space compared to discrete solutions.

Replacement Considerations

Direct pin-compatible replacements include the 74AHC3G14DC variant, which shares the same VSSOP8 package but utilizes CMOS input levels instead of TTL. Designers must verify input threshold compatibility when substituting between AHC and AHCT series parts.
