74HC14N

Overview

The TAEJIN 74HC14N is a hex inverting Schmitt trigger integrated circuit housed in a DIP-14 package. It operates within a supply voltage range of 2.0V to 6.0V and features low power consumption with a maximum quiescent current of 20µA. The device provides an output drive capability of ±4mA at 5.0V and supports up to 10 LSTTL loads. Typical propagation delay is 11ns, with a maximum input leakage current of 1µA.

Feature Summary

• Contains six independent inverter circuits with Schmitt-trigger inputs for signal conditioning
• Provides hysteresis to convert slow-rising or noisy input signals into clean square waves
• Outputs are compatible with standard CMOS outputs and can drive multiple LSTTL loads

Applications

• Microwave ovens
• Printers
• AC inverter drives
• Uninterruptible Power Supplies (UPS)
• AC servo drives

Procurement Notes

Verify the manufacturer origin as TAEJIN when sourcing this component, as the 74HC14N designation is widely used by various semiconductor producers including Texas Instruments and NXP. Confirm that the specific datasheet matches the HTC Korea source provided. Ensure the DIP-14 package type aligns with your board design requirements before finalizing procurement orders.

Selection Notes

Select the 74HC14N when application logic requires noise immunity or waveform shaping rather than simple inversion. The Schmitt trigger inputs make it suitable for environments with signal interference. Verify that the operating temperature range of -40°C to 85°C meets your environmental constraints. Consider the DIP-14 package availability if through-hole mounting is necessary for your assembly process.

Part Context

This component belongs to the 74HC series of high-speed CMOS logic devices. It performs the Boolean function Y = A' in positive logic. The device consists of six single-stage inverters, where each inverter utilizes Schmitt-trigger technology to ensure stable switching thresholds regardless of input signal slope.

Replacement Considerations

Direct pin-compatible substitutes include the 74HC14D (SOP-14 package) from the same manufacturer family. Other generic equivalents exist across different vendors, but verify electrical characteristics such as propagation delay and output drive current to ensure functional parity.
