CD74HCT14EX

Inverter Gates Overview

The CD74HCT14EX is a hex Schmitt-trigger inverter manufactured by Harris Corporation. It features six independent inverters with Schmitt-trigger inputs, designed for noise immunity and waveform shaping. The device operates within a supply voltage range of 4.5V to 5.5V and supports propagation delays up to 38ns at 4.5V with a 50pF load. It is housed in a 14-pin Dual In-line Package (DIP) with a 0.300-inch (7.62mm) width, suitable for through-hole mounting.

Inverter Gates Feature Summary

• Hex configuration providing six independent Schmitt-trigger inverters
• Schmitt-trigger input action eliminates noise-induced false triggering
• CMOS technology ensures low power consumption and high noise immunity
• Compatible with standard TTL logic levels

Inverter Gates Applications

• Waveform shaping from slowly changing signals
• Oscillator circuits requiring stable threshold voltages
• Noise filtering in digital signal paths
• Pulse generation and timing applications

Inverter Gates Procurement Notes

Verify the manufacturer designation as Harris Corporation on the component marking. Confirm the package type is 14-DIP (0.300 inch). Check RoHS compliance status, as older Harris production may not meet current environmental standards. Ensure the suffix 'EX' corresponds to bulk packaging if required by assembly processes.

Inverter Gates Selection Notes

Select this component when noise immunity is critical for inverting slow-rise-time signals. The HCT series ensures compatibility with 5V CMOS and TTL logic families. Consider the DIP-14 package for prototyping or legacy board designs requiring through-hole technology. Verify operating temperature range requirements against the specified -55°C to 125°C limit.

Inverter Gates Part Context

This part belongs to the 74HCT logic family, which bridges CMOS performance with TTL compatibility. The CD74HCT14 variant specifically provides hex inverters with Schmitt triggers. Harris Corporation was a primary manufacturer before its semiconductor assets were acquired by other entities, affecting current sourcing channels.

Inverter Gates Replacement Considerations

Cross-reference with Texas Instruments CD74HCT14E or CD74HCT14M for equivalent functionality. Verify pinout compatibility and electrical characteristics match the original design requirements. Note that package variations (DIP vs SOIC) require mechanical footprint adjustments.
