74AHC3G14DP,125

Overview

The Nexperia 74AHC3G14DP,125 is a triple inverting Schmitt trigger housed in an SOT505-2 (TSSOP8) package. It operates within a supply voltage range of 2.0 V to 5.5 V and features overvoltage tolerant inputs up to 5.5 V. The device provides symmetrical output impedance and balanced propagation delays. Static characteristics include a maximum input leakage current of 2.0 μA at -40 °C to +125 °C. Dynamic performance specifies a maximum propagation delay of 13.5 ns at 5.5 V with 50 pF load capacitance across the extended temperature range.

Feature Summary

• Triple inverter configuration with Schmitt-trigger inputs for noise immunity
• Overvoltage tolerant inputs allowing operation in mixed voltage environments
• Symmetrical output impedance with balanced propagation delays
• High ESD protection exceeding 2000 V HBM and 1000 V CDM

Applications

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

Selection Notes

Select this component when a triple inverter with Schmitt-trigger action is required for signal conditioning. The TSSOP8 package suits applications needing moderate pin density with standard surface mount assembly. Ensure the design accommodates the specified power dissipation derating curves for the SOT505-2 package above 96 °C ambient temperature.

Part Context

This part belongs to the 74AHC family of high-speed CMOS logic devices manufactured by Nexperia. The 74AHC3G14 series includes variants in different packages such as VSSOP8 and XSON8. The DP suffix specifically denotes the thin shrink small outline plastic package with 8 leads.

Replacement Considerations

Direct functional equivalents include the 74AHCT3G14DP for TTL-level input compatibility and other package variants like 74AHC3G14DC or 74AHC3G14GT from the same manufacturer.
