74HCT3G14DC,125

Overview

The Nexperia 74HCT3G14DC,125 is a triple inverting Schmitt trigger integrated circuit belonging to the HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features three independent inverters with Schmitt-trigger inputs in an 8-TSSOP surface-mount package. The device provides high noise immunity and transforms slowly changing input signals into sharply defined output signals. It supports a maximum propagation delay of 32 ns at 4.5 V with 50 pF load and offers output drive currents of 4 mA for both high and low states.

Feature Summary

• Triple inverting buffers with Schmitt-trigger inputs for jitter-free signal generation
• TTL-compatible input levels ensuring direct interface with standard TTL logic
• High noise immunity suitable for noisy environments

Applications

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

Procurement Notes

Verify the specific suffix DC,125 against official Nexperia documentation to confirm the VSSOP-8 packaging and tape-and-reel quantity specifications. Ensure the design requires HCT logic levels rather than HC or LVC variants. Confirm that the 4.5 V to 5.5 V supply range aligns with the target system power rails before finalizing procurement.

Selection Notes

Select this component when TTL-level compatibility is required alongside Schmitt-trigger noise filtering. It is appropriate for designs needing three inverters in a compact surface-mount footprint. Consider alternative packages like TSSOP if lead length requirements differ. Verify that the 32 ns propagation delay meets the timing constraints of the application circuit.

Part Context

This part belongs to the 74HCT3G14 series of triple inverters. It shares functional similarities with the 74HC3G14 but utilizes HCT technology for TTL input compatibility. The DC suffix denotes the VSSOP-8 package variant, distinguishing it from other package options such as TSSOP or XSON available within the same logical family.
