N74F14D,602

Inverter Gates Overview

The N74F14D,602 is a hex inverter Schmitt trigger integrated circuit manufactured by NXP USA Inc. It accepts standard TTL input signals and provides standard TTL output levels. The device transforms slowly changing input signals into sharply defined, jitter-free outputs with greater noise margin than conventional inverters. Each circuit contains a Schmitt trigger followed by a Darlington level shifter and a phase splitter driving a TTL totem-pole output. It operates within a supply voltage range of 4.5V to 5.5V and features a propagation delay of 5.0ns typical at VCC=5V.

Inverter Gates Feature Summary

• Contains six logic inverters with Schmitt trigger inputs for signal conditioning
• Transforms slowly changing input signals into sharply defined, jitter-free outputs
• Provides greater noise margin compared to conventional inverters
• Uses positive feedback to speed up slow input transitions

Inverter Gates Applications

• Signal conditioning for slowly changing waveforms
• Jitter-free output generation from noisy inputs
• TTL logic interface applications requiring hysteresis

Inverter Gates Procurement Notes

Verify the specific suffix '602' against official NXP documentation to confirm package type and temperature range compliance. Confirm current production status as datasheets indicate potential obsolescence or lifecycle changes. Ensure compatibility with 4.5V to 5.5V supply requirements and 14-SOIC packaging constraints before procurement.

Inverter Gates Selection Notes

Select this component when input signals exhibit slow rise/fall times or significant noise that requires hysteresis for clean switching. It is suitable for designs needing TTL-compatible outputs with enhanced noise immunity. Consider the 14-SOIC package dimensions and commercial temperature range (0°C to +70°C) if industrial range is not required.

Inverter Gates Part Context

This part belongs to the 74F series of high-speed TTL logic devices. The 'D' suffix indicates a 14-pin plastic small outline package (SO). The 'N74F14' base model denotes a hex inverter with Schmitt triggers. NXP acquired Philips Semiconductors, continuing the legacy of these logic families.

Inverter Gates Replacement Considerations

Check for direct equivalents such as the N74F14N for DIP packaging or other manufacturers' 74F14 variants. Verify pinout compatibility and electrical characteristics match before substitution.

Inverter Gates FAQ

What is the function of the Schmitt trigger in this device?

The Schmitt trigger uses positive feedback to effectively speed up slow input transitions and provide different input threshold voltages for positive-going and negative-going inputs, ensuring jitter-free output.

What is the typical propagation delay for the N74F14D,602?

The typical propagation delay is 5.0ns at VCC = 5V.
