74HC14D

Overview

The TAEJIN 74HC14D is a hex Schmitt trigger inverter fabricated using CMOS technology. It contains six independent inverters performing the Boolean function Y = A̅. The device operates within a supply voltage range of 2.0V to 6.0V and features an operating free-air temperature range from -40°C to 85°C. It provides typical propagation delays of 11ns at 6V and output drive capabilities of ±4mA at 5.0V. The package configuration is SOP-14.

Feature Summary

• Incorporates Schmitt-trigger inputs to convert slowly changing signals into clearly defined outputs
• Capable of driving up to 10 LSTTL loads
• Features low power consumption with maximum quiescent current of 20µA

Applications

• Microwave ovens
• Printers
• AC inverter drives
• UPS systems
• Motor drives

Procurement Notes

Verify the manufacturer designation on the component marking, as the source material identifies HTC as the producer for the 74HC14D part number. Confirm the SOP-14 package type matches the design requirements. Ensure the application environment remains within the specified -40°C to 85°C operating temperature range for guaranteed functionality.

Selection Notes

Select this component when slow-rising input signals require noise immunity provided by Schmitt triggers. It serves as a direct functional replacement for standard 74HC14 devices in SOP-14 packages. Consider the 2.0V to 6.0V supply range compatibility with existing system voltages before integration.

Part Context

This component belongs to the 74HC logic family, which offers high-speed CMOS performance compatible with Low-power Schottky TTL (LSTTL) standards. The 'D' suffix specifically denotes the SOP-14 surface-mount package variant, distinguishing it from through-hole DIP options.

Replacement Considerations

Standard equivalents include SN74HC14D and NTE74HC14D. Verify pinout compatibility and electrical characteristics against the original design specifications before substitution.
