SN7414DG4

Overview

The SN7414DG4 is a hex Schmitt-trigger inverter manufactured by Texas Instruments. It integrates six independent inverters within a single 14-pin Small Outline Integrated Circuit (SOIC) package. Designed for TTL/H/L logic families, the device operates across a standard temperature range of 0°C to 70°C. The component features a maximum low-level output current of 16 mA and supports a load capacitance of 15 pF. It complies with RoHS standards and is lead-free.

Feature Summary

• Integrates six independent Schmitt-trigger inverters for signal conditioning
• Provides noise filtering and waveform shaping through defined hysteresis
• Compatible with standard TTL and CMOS logic systems

Applications

• Signal conditioning for noisy digital environments
• Waveform shaping from slow or distorted input signals
• Pulse generation circuits requiring precise threshold control

Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's latest documentation to confirm compliance with current environmental directives and material declarations. Ensure the ordering part number matches the required package style and temperature rating. Cross-reference the datasheet revision date to validate all electrical characteristics before finalizing procurement specifications.

Selection Notes

Select this component when multiple inverting stages with noise immunity are required in a compact surface-mount footprint. The Schmitt-trigger action makes it suitable for interfaces where input signals may exhibit slow rise times or significant electrical noise. Verify that the operating voltage and load requirements align with the standard logic family specifications provided in the official data sheet.

Part Context

This device belongs to the standard 74-series logic family, specifically designed as a hex inverter with Schmitt-trigger inputs. It serves as a fundamental building block for digital logic applications requiring clean switching transitions. The SOIC-14 package offers a balance between pin count and board space efficiency for general-purpose integrated circuit designs.

Replacement Considerations

Direct replacements include other SN7414 variants with compatible packages and electrical ratings. Verify that substitute components maintain the same Schmitt-trigger characteristics and package dimensions to ensure mechanical and functional compatibility without redesigning the host circuit.
