74HC14N,652

Overview

The 74HC14N,652 is a high-speed silicon-gate CMOS hex inverting Schmitt trigger manufactured by NXP Semiconductors. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device features six independent inverting buffers with Schmitt-trigger action, transforming slowly changing input signals into sharply defined output signals. It provides ESD protection exceeding 2000 V (HBM) and 200 V (MM). The component is housed in a 14-lead plastic dual in-line package (DIP14, SOT27-1) designed for through-hole mounting.

Feature Summary

• Provides six independent inverting buffers with Schmitt-trigger action for signal conditioning
• Capable of transforming slowly changing input signals into sharply defined, jitter-free output signals
• Offers robust electrostatic discharge (ESD) protection exceeding specified Human Body Model and Machine Model thresholds

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific ordering suffix '652' against current NXP documentation to confirm package type and temperature grade. Confirm RoHS compliance status as indicated in the latest product data sheet. Ensure the DIP14 package variant matches the intended PCB footprint requirements. Check for any recent lifecycle status updates regarding production availability.

Selection Notes

Select this component when slow-rising input signals require noise immunity provided by Schmitt-trigger hysteresis. The HC logic family ensures compatibility with standard CMOS levels across a wide voltage range. Verify that the required operating temperature extends to +125 °C, as this specific part number covers the extended industrial range compared to standard commercial variants.

Part Context

This component belongs to the 74HC/HCT logic family, which is pin-compatible with Low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard No. 7A. The 'HC' designation indicates high-speed CMOS technology, while the '14' functional code identifies it as a hex inverter with Schmitt triggers. The 'N' suffix denotes the PDIP package style.

Replacement Considerations

Direct pin-compatible replacements include other manufacturers' 74HC14 devices in DIP-14 packages. Cross-reference with 74HCT14N if TTL-level input compatibility is required instead of CMOS levels. Verify that any substitute maintains the same extended temperature rating (-40 °C to +125 °C) and Schmitt-trigger characteristics.
