CD74HCT14E

Inverter Gates Overview

The CD74HCT14E is a hex Schmitt-trigger inverter manufactured by Harris Corporation, belonging to the HCT logic series. It features six independent inverters with Schmitt-trigger inputs for noise immunity and CMOS push-pull outputs. The device operates within a supply voltage range of 4.5V to 5.5V and supports a maximum propagation delay of 57ns at specified load capacitance. Output drive capabilities include a low-level current of 4mA and a high-level current of -4mA. It is housed in a 14-pin PDIP package designed for through-hole mounting, functioning reliably across an extended temperature range from -55°C to 125°C.

Inverter Gates Feature Summary

• Integrates six independent Schmitt-trigger inverters to provide enhanced noise immunity for signal conditioning applications.
• Features CMOS push-pull outputs capable of driving standard TTL loads while maintaining compatibility with HCT logic families.
• Supports operation over an extended industrial temperature range suitable for demanding environmental conditions.

Inverter Gates Applications

• Signal waveform shaping and conversion of slow-rise or slow-fall input signals into clean digital pulses
• Noise filtering and threshold detection in digital communication interfaces
• Oscillator circuit design utilizing RC timing networks

Inverter Gates Procurement Notes

Verify the manufacturer designation on the component marking, as Harris Corporation logic assets were acquired by Texas Instruments. Confirm that the specific part number corresponds to the original Harris production run rather than subsequent TI manufacturing. Ensure the package type matches the required 14-pin DIP configuration for your PCB layout constraints.

Inverter Gates Selection Notes

Select this component when Schmitt-trigger action is required to eliminate signal chatter or noise on digital lines. The HCT series ensures direct interface compatibility with standard TTL circuits without level shifting requirements. Consider the 14-pin DIP package availability if through-hole assembly is mandated by the design specifications.

Inverter Gates Part Context

This component belongs to the CD74HCT14 family of hex inverters. It shares functional similarities with other devices in the HCT logic family, such as the CD74HC14, but offers improved noise immunity due to its Schmitt-trigger inputs. The device serves as a fundamental building block for digital logic circuits requiring signal regeneration and threshold control.
