MM74HCT14SJ

Inverter Gates Overview

The MM74HCT14SJ is a hex inverting Schmitt trigger integrated circuit manufactured by Fairchild Semiconductor. It operates within a supply voltage range of 4.5V to 5.5V and features six independent inverters with Schmitt-trigger inputs for noise immunity. The device utilizes CMOS technology and is housed in a 14-SOP package. Key electrical parameters include a maximum propagation delay of 20ns at 5V with 50pF load, output currents of 4.8mA high and low, and a maximum quiescent current of 1µA. It supports an operating temperature range from -40°C to 85°C.

Inverter Gates Feature Summary

• Hex inverting Schmitt trigger configuration provides noise immunity through hysteresis
• CMOS technology ensures low power consumption and high noise immunity
• Compatible with standard logic families for direct interface applications

Inverter Gates Applications

• Signal conditioning for noisy digital environments
• Pulse generation and waveform shaping
• Oscillator circuits requiring stable switching thresholds

Inverter Gates Procurement Notes

Verify the specific suffix SJ against the manufacturer's official documentation to confirm package dimensions and pinout compatibility. Ensure the source component matches the required HCT logic family specifications. Cross-reference the manufacturer part number with current ON Semiconductor listings due to corporate integration changes. Confirm RoHS compliance status via the latest datasheet revision before procurement.

Inverter Gates Selection Notes

Select this component when Schmitt trigger functionality is required within the 74HCT logic family constraints. The 4.5V to 5.5V supply range limits usage to standard 5V systems. Compare propagation delays and output drive capabilities against alternative HCT inverters if timing or load requirements exceed standard specifications. Verify package availability in SOP-14 format for PCB layout compatibility.

Inverter Gates Part Context

This component belongs to the 74HCT series of high-speed CMOS logic devices originally produced by Fairchild Semiconductor. Following the acquisition of Fairchild by ON Semiconductor, product lines were consolidated under the ON Semi brand. The MM74HCT14SJ represents the surface-mount SOP variant of the standard hex inverter Schmitt trigger function within this widely used industrial logic family.

Inverter Gates Replacement Considerations

Public confirmed substitute part numbers include MM74HCT14MTCX and MM74HCT14M. These alternatives share identical logical functions and pinouts but may differ in packaging style such as TSSOP or standard SOIC. Verify mechanical fit and thermal characteristics when substituting.
