74HCT14N,652

Overview

The 74HCT14N,652 is a hex inverting Schmitt trigger manufactured by Nexperia. It features six independent inverters with Schmitt-trigger inputs designed to transform slowly changing signals into sharply defined outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. It utilizes a 14-pin PDIP package for through-hole mounting.

Feature Summary

• Schmitt-trigger inputs provide high noise immunity and eliminate output jitter from slowly changing input signals.
• CMOS low power dissipation characteristics suitable for energy-efficient designs.
• Inputs include clamp diodes allowing interface to voltages exceeding VCC using current limiting resistors.

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm package type and temperature grade. Confirm RoHS compliance status and check for any product change notices or end-of-life announcements prior to finalizing procurement plans.

Selection Notes

Select this component when TTL logic level interfacing is required alongside Schmitt trigger noise rejection capabilities. Ensure the application environment remains within the specified -40 °C to +125 °C operating temperature range and that the supply voltage stays between 4.5 V and 5.5 V.

Part Context

This part belongs to the 74HCT series of high-speed silicon-gate CMOS devices. It is pin-compatible with low-power Schottky TTL (LSTTL) standards. The device complies with JEDEC standard no. 7A and offers ESD protection exceeding 2000 V according to HBM testing.

Replacement Considerations

Cross-reference with other manufacturers' 74HCT14 equivalents ensuring identical pinout and electrical specifications. Verify that alternative packages match the physical footprint requirements if form-factor constraints exist.
