74HCT3G14DP,125

Overview

The 74HCT3G14DP,125 is a triple inverter with Schmitt-trigger inputs manufactured by Nexperia. It operates within a supply voltage range of 4.5 V to 5.5 V and features overvoltage tolerant inputs. The device provides three independent inverting channels with Schmitt-trigger action for noise immunity. It is specified for operation from -40 °C to +125 °C. The maximum propagation delay is 32 ns at 4.5 V with a 50 pF load. Output currents are rated at 4 mA for both high and low states. The component is housed in an 8-TSSOP package.

Feature Summary

• Triple inverter configuration with Schmitt-trigger inputs for enhanced noise immunity
• Overvoltage tolerant inputs suitable for mixed voltage environments
• 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 125 corresponds to the required tape and reel or cut tape packaging format. Confirm that the 8-TSSOP package dimensions align with the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number with official distributor catalogs to validate current availability status.

Selection Notes

Select this component when TTL-level input compatibility is required alongside Schmitt-trigger noise filtering. The HCT logic family ensures compatibility with standard TTL outputs while offering CMOS performance. Consider the 8-TSSOP package for surface-mount applications requiring compact layout. Verify that the 4.5 V to 5.5 V supply voltage range matches the system power rails.
