SN7414N

Overview

The SN7414N is a hex inverter from the Texas Instruments 74 logic family, featuring Schmitt-trigger inputs for noise immunity. It operates within a supply voltage range of 4.75V to 5.25V and supports a maximum propagation delay of 22ns. The device provides a low-level output current of 16mA and a high-level output current of -0.8mA. Packaged in a 14-pin PDIP for through-hole mounting, it functions reliably across an operating temperature range of 0°C to 70°C.

Feature Summary

• Integrates six independent inverters with Schmitt-trigger input thresholds to filter noisy signals.
• Provides robust low-level sink current capability for driving loads effectively.
• Designed for standard 5V logic systems with defined high and low output drive characteristics.

Applications

• Signal conditioning for noisy digital environments
• Pulse generation and waveform shaping
• Oscillator circuits requiring hysteresis

Procurement Notes

Verify the specific manufacturer lot and date code upon receipt to ensure component authenticity. Confirm that the physical package matches the specified 14-pin PDIP form factor. Check datasheet revisions for any updates regarding electrical characteristics or handling instructions before final integration into the design.

Selection Notes

Select this component when signal integrity is compromised by noise, as the Schmitt trigger action prevents false triggering caused by slow-rising edges. It is suitable for applications requiring simple inversion with enhanced noise tolerance compared to standard logic gates without hysteresis.

Part Context

This part belongs to the industry-standard 74 logic series, widely used for general-purpose digital logic operations. The SN7414 variant specifically addresses the need for input buffering and wave shaping in TTL-compatible systems, serving as a fundamental building block for timing and control circuits.

Replacement Considerations

Compatible substitutes include other hex Schmitt trigger inverters such as the SN74LS14N or SN74HC14N, provided voltage levels and speed requirements align with the system design constraints.
