MC74VHC1GT04DFT3G

Inverter Gates Overview

The MC74VHC1GT04DFT3G is a single inverter from the 74VHC logic family, manufactured by onsemi. It operates within a supply voltage range of 2.0 V to 5.5 V and features TTL-compatible input thresholds. The device provides over-voltage tolerant inputs and outputs up to 5.5 V, enabling safe interfacing between 5 V and 3 V circuits. It supports partial power-down protection via IOFF and delivers source/sink currents of 8 mA at 3.0 V. Packaged in SC-88A (SOT-353), it utilizes advanced high-speed CMOS technology with chip complexity under 100 FETs.

Inverter Gates Feature Summary

• TTL-compatible input thresholds for direct interface with TTL logic sources
• Over-voltage tolerant I/O structures allowing operation with voltages up to 5.5 V regardless of supply level
• Partial power-down protection capability through IOFF support to prevent excessive current draw during power-off states

Inverter Gates Applications

• Interfacing 5 V digital circuits with 3 V logic systems
• Signal inversion in portable battery-powered devices
• Level shifting applications requiring robust input protection against hot insertion or supply mismatch

Inverter Gates Procurement Notes

Verify the specific ordering suffix DFT3G corresponds to the SC-88A package variant with a shipping quantity of 10,000 units per tape and reel. Confirm that the -Q suffix is not required if automotive qualification or PPAP capability is not needed for the target application. Ensure compliance with RoHS and halogen-free material requirements as specified in the datasheet.

Inverter Gates Selection Notes

Select this component when TTL-level input recognition is necessary within a 74VHC family design. The device is suitable for applications requiring over-voltage tolerance on both inputs and outputs without external protection components. Consider the SC-88A package for compact surface-mount designs where space is limited but higher volume reel packaging is preferred.

Inverter Gates Part Context

This part belongs to the MC74VHC1G04/MC74VHC1GT04 series of single inverters. The GT04 designation specifically indicates TTL-compatible input thresholds, distinguishing it from the standard G04 which uses CMOS thresholds. Both variants share identical electrical characteristics regarding speed, drive strength, and power consumption, differing only in input threshold voltage definitions.

Inverter Gates Replacement Considerations

MC74VHC1GT04DFT1G: Identical function and package; differs in shipping quantity (3,000 units vs. 10,000 units). MC74VHC1GT04DFT2G: Identical function and package; differs in shipping quantity (3,000 units) and potentially pin orientation or reel specifications.
