MC74VHC1GT50DFT2G-Q

Overview

The MC74VHC1GT50DFT2G-Q is a single-channel, non-inverting buffer from the onsemi 74VHC series. It operates within a supply voltage range of 2.0 V to 5.5 V and features TTL-compatible input thresholds. The device provides push-pull outputs capable of sourcing and sinking 8 mA at 3.0 V. It includes over-voltage tolerant inputs and outputs up to 5.5 V, supporting partial power-down protection via IOFF. Propagation delay is typically 3.5 ns at 5 V with a 15 pF load. It is housed in an SC-88A (SOT-353) package.

Feature Summary

• TTL level input thresholds for direct interfacing with 5 V circuits
• Over-voltage tolerant I/O structures up to 5.5 V regardless of supply voltage
• IOFF feature supports partial power down protection
• Advanced high-speed CMOS technology in a tiny footprint

Applications

• Interface between 5 V and 3 V logic circuits
• Portable equipment requiring low power consumption
• Battery-powered systems

Procurement Notes

Verify that the suffix -Q indicates AEC-Q100 qualification and PPAP capability as specified in the datasheet ordering information. Confirm the specific device code and pin orientation match the required application design. Ensure compliance with RoHS and halogen-free requirements stated in the product features.

Selection Notes

Select this component when TTL-level input compatibility is required alongside high-speed buffering capabilities. The SC-88A package offers a compact solution for space-constrained designs. Consider the 8 mA output drive strength and over-voltage tolerance for robust signal integrity in mixed-voltage environments.

Part Context

This part belongs to the MC74VHC1G50/MC74VHC1GT50 family of advanced high-speed CMOS buffers. The 'T' designation specifically denotes TTL input thresholds, distinguishing it from the standard VHC logic which uses CMOS thresholds. The '-Q' suffix identifies it as an automotive-grade or qualified variant meeting specific site and control change requirements.
