Overview
The 74AHCT3G14GD,125 is a triple inverting Schmitt trigger manufactured by Nexperia. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL input levels with overvoltage tolerance up to 5.5 V. The device provides symmetrical output impedance and high noise immunity. It supports an ambient temperature range from -40 °C to +125 °C and includes ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). Propagation delay is typically 4.1 ns at 5.0 V with 15 pF load.
Feature Summary
- Triple inverting Schmitt trigger configuration
- TTL-compatible input logic levels
- Overvoltage tolerant inputs up to 5.5 V
- High noise immunity and low power dissipation
Applications
- Wave and pulse shaping in noisy environments
- Astable multivibrator circuits
- Monostable multivibrator circuits
Procurement Notes
Verify the specific package suffix GD corresponds to the required XSON8 form factor during procurement. Confirm that the ordering code matches the intended temperature grade and electrical specifications. Ensure compatibility with existing PCB footprints for the SOT833-1 outline before finalizing orders.
Selection Notes
Select this component when TTL-level interfacing is required alongside Schmitt-trigger action for signal conditioning. It is suitable for mixed-voltage applications due to input overvoltage tolerance. Consider the XSON8 package constraints regarding thermal dissipation and board space requirements compared to larger packages.
Part Context
This part belongs to the 74AHCT3G14 family of triple inverters with Schmitt triggers. It utilizes CMOS technology optimized for 5 V operation. The 'GD' suffix indicates the XSON8 plastic extremely thin small outline package variant without leads, designed for compact surface-mount applications.
Replacement Considerations
Check for direct pin-compatible alternatives within the same logic family if the XSON8 package is unavailable. Verify that any substitute maintains the same TTL input thresholds and Schmitt trigger hysteresis characteristics to ensure circuit stability.
