MM74HCT14SJ

Inverter Gates Overview

The MM74HCT14SJ is a hex Schmitt-trigger inverter manufactured by onsemi, utilizing high-performance silicon-gate CMOS technology. It operates within a supply voltage range of 4.5 V to 5.5 V and features LSTTL-compatible inputs. The device provides six independent inverting channels with hysteresis for noise immunity. It supports output drive capabilities equivalent to ten LSTTL loads and interfaces directly with CMOS, NMOS, and TTL logic families.

Inverter Gates Feature Summary

• Hex Schmitt-trigger inverter configuration
• LSTTL compatible input levels
• High noise immunity via hysteresis
• Direct interface to CMOS, NMOS, and TTL

Inverter Gates Applications

• Level conversion from TTL or NMOS outputs to high-speed CMOS inputs
• Signal conditioning to square up slow rise and fall times
• Operation in noisy environments requiring noise filtering

Inverter Gates Procurement Notes

Verify the package type against project requirements, as the SJ suffix typically indicates a SOIC-14 package. Confirm RoHS compliance status and check for any specific environmental declarations such as REACH material disclosures. Ensure the operating temperature range meets system specifications before finalizing procurement.

Inverter Gates Selection Notes

Select this component when interfacing legacy TTL or NMOS sources with modern high-speed CMOS circuits. The Schmitt trigger input is essential for cleaning up signals with slow transitions or significant noise. Verify that the 4.5V to 5.5V supply range aligns with the target system power rails.

Inverter Gates Part Context

This part belongs to the 74HCT series of high-speed CMOS logic devices. It serves as a digital logic inverter with built-in Schmitt trigger functionality. The device is designed for general-purpose digital applications requiring robust signal integrity and compatibility with standard logic families.

Inverter Gates Replacement Considerations

Compatible substitutes include the MM74HCT14MTCX (TSSOP-14) and MM74HCT14M (SOIC-14). Cross-reference pinouts and electrical characteristics carefully when replacing components to ensure functional equivalence.
