MC74VHC1GT14DF2G

Inverter Gates Overview

The MC74VHC1GT14DF2G is a single Schmitt-trigger inverter manufactured by onsemi using high-speed CMOS technology. It operates within a supply voltage range of 2.0 V to 5.5 V and features TTL-level input thresholds. The device provides buffered output for high noise immunity and stable performance. Input and output structures offer protection against voltages up to 5.5 V, enabling safe interfacing between 5 V and 3 V circuits. It supports partial power-down via IOFF and includes over-voltage tolerance regardless of the supply voltage state.

Inverter Gates Feature Summary

• Schmitt-trigger input action ensures clean signal transitions and high noise immunity
• TTL-level input thresholds allow direct interface with 5 V logic systems
• Over-voltage tolerant inputs and outputs protect against voltage mismatches
• IOFF feature supports partial power-down mode to minimize standby current

Inverter Gates Applications

• Interfacing 5 V logic circuits with 3 V logic systems
• Signal conditioning for noisy digital environments
• Pulse width modulation (PWM) signal generation
• Oscillator circuit design requiring precise threshold control

Inverter Gates Procurement Notes

Verify the specific suffix DF2G against official datasheets to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS3 standards if required by your manufacturing process. Confirm that the TTL threshold variant matches your system's logic levels rather than the standard CMOS version. Check for automotive qualification requirements if the application demands AEC-Q100 compliance.

Inverter Gates Selection Notes

Select this component when a single inverter with hysteresis is needed in a minimal footprint. The TTL threshold variant is essential for driving from 5 V sources directly into lower voltage domains without level shifting resistors. Consider the 8 mA drive capability for moderate load requirements. Verify that the SC-88A or equivalent package fits the board space constraints compared to larger alternatives.

Inverter Gates Part Context

This part belongs to the MC74VHC1G series of single-gate logic devices. It shares functional similarities with the MC74VHC1G14 but differs in input threshold characteristics. The MC74VHC1G14 uses CMOS thresholds, while the MC74VHC1GT14 utilizes TTL thresholds. This distinction determines its suitability for interfacing with different logic families.
