MM74HC14SJ

Inverter Gates Overview

The MM74HC14SJ is a hex Schmitt trigger inverter manufactured by onsemi. It contains six independent inverters, each with one input and one output, housed in a 14-SOP surface-mount package. The device operates within a supply voltage range of 2V to 6V. It features high noise immunity due to hysteresis, symmetrical output impedance with minimum source/sink currents of 4mA, and balanced propagation delays. The component supports ESD protection levels of 1kV CDM, 2kV HBM, and 200V MM.

Inverter Gates Feature Summary

• Hex Schmitt trigger inverter configuration for signal conditioning
• High noise immunity via hysteresis for slow rise/fall times
• Symmetrical output impedance with balanced propagation delays
• Integrated ESD protection circuits against static discharge

Inverter Gates Applications

• Line receivers with slow input signals
• Noisy environment signal squaring
• Pulse width modulation generation
• Oscillator circuits requiring hysteresis

Inverter Gates Procurement Notes

Verify the specific suffix SJ corresponds to the 14-SOP package variant when sourcing. Confirm RoHS compliance status as manufacturing practices may vary by production batch. Check current part status as legacy logic families often face obsolescence. Ensure the supplier provides official datasheets matching the MM74HC14 designation to avoid pinout mismatches with similar series components.

Inverter Gates Selection Notes

Select this component when CMOS logic compatibility is required alongside Schmitt trigger noise rejection. It serves as a direct pin-compatible replacement for standard HC04 inverters where signal integrity is compromised by noise or slow transitions. Consider the 2V to 6V operating range for applications needing flexibility between lower voltage systems and traditional 5V logic levels without level shifting.

Inverter Gates Part Context

This component belongs to the 74HC family of high-speed CMOS logic devices. It shares identical pinouts with the LS14, LS04, and HC04 series, facilitating drop-in replacements in existing designs. The device utilizes silicon gate CMOS technology to achieve high performance while maintaining low power dissipation characteristics typical of modern CMOS logic families.

Inverter Gates Replacement Considerations

Direct pin-compatible substitutes include MC74HC14DG and M74HC14 variants from onsemi. Other manufacturers offer equivalent parts such as NXP 74HC14 or Diodes Incorporated 74HC14. Verify that alternative sources maintain the same SOP-14 footprint and electrical specifications for seamless integration.
