MC74VHC1GT50MU2TCG

Overview

The MC74VHC1GT50MU2TCG is a single-channel non-inverting buffer from the onsemi VHC logic family, designed for high-speed CMOS applications. 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, ensuring protection against supply mismatches. It supports partial power-down via IOFF functionality and delivers source/sink currents of 8 mA at 3.0 V. Propagation delay is typically 3.5 ns at 5 V with a 15 pF load. The component is housed in a UDFN6 package (Case 517AA) measuring 1.2 x 1.0 mm.

Feature Summary

• TTL level input thresholds compatible with standard digital logic families
• Over-voltage tolerant I/O structures protecting against voltage mismatches up to 5.5 V
• IOFF feature enables partial power-down protection to minimize leakage current
• Advanced high-speed CMOS technology optimized for low power consumption

Applications

• Interfacing 5 V circuits to 3 V circuits
• High-speed data bus buffering
• Clock signal distribution
• Portable battery-powered devices

Procurement Notes

Verify the specific ordering suffix MU2TCG corresponds to the UDFN6 1.2x1.0 mm package configuration. Confirm RoHS compliance and Pb-free status through official manufacturer documentation. Ensure the application environment remains within the specified -55°C to +125°C operating temperature range. Validate that input voltages do not exceed the absolute maximum ratings defined in the datasheet.

Selection Notes

Select this component when TTL-level input compatibility is required alongside high-speed performance in a minimal footprint. The UDFN6 package offers space efficiency for dense PCB layouts. Consider the 8 mA drive capability for moderate capacitive loads. Verify that the 2.0 V minimum supply voltage aligns with the system power architecture requirements.

Part Context

This part belongs to the MC74VHC1GT50 series, which includes variants in SC-88A, SOT-553, and other packages. The 'MU' suffix specifically denotes the UDFN6 case style. It shares functional characteristics with the MC74VHC1G50 but differs in input threshold levels, providing TTL compatibility instead of CMOS thresholds.
