MC74VHC1GT50MU1TCG

Overview

The MC74VHC1GT50MU1TCG is a single-channel, non-inverting buffer from the MC74VHC1GT50 series, fabricated using advanced 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 over-voltage tolerant inputs and outputs up to 5.5 V, enabling safe interfacing between 5 V and 3 V logic circuits. It supports partial power-down protection via IOFF 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. It is housed in a UDFN6 package (1.45 x 1.0 mm) and is RoHS compliant.

Feature Summary

• TTL level input thresholds for direct compatibility with standard logic families
• Over-voltage tolerant I/O structures protect against supply mismatches and hot insertion
• IOFF feature enables partial power-down protection to minimize leakage current

Applications

• Interfacing 5 V circuits to 3 V circuits
• High-speed signal buffering in portable devices
• Partial power-down protection in battery-backed systems

Procurement Notes

Verify the specific ordering suffix MU1TCG corresponds to the UDFN6 1.45 x 1.0 mm package with R pin orientation. Confirm RoHS compliance and Pb-free status as indicated by the /C0071 marking. Ensure tape and reel specifications match the required quantity per manufacturer brochure BRD8011/D. Check for any -Q suffix requirements if automotive qualification is needed.

Selection Notes

Select this component when TTL input thresholds are required rather than CMOS thresholds found in the MC74VHC1G50 variant. Choose the UDFN6 package for minimal footprint constraints where SC-88A or SOT-553 options are unsuitable. Verify that the 3.5 ns propagation delay meets system timing requirements under the intended operating voltage and load conditions.

Part Context

This part belongs to the MC74VHC1GT50 family of single-buffer logic ICs. It shares functional similarities with the MC74VHC1G50 but differs in input threshold characteristics. The device is designed for applications requiring robust I/O protection and low power consumption in compact surface-mount packages.

Replacement Considerations

MC74VHC1G50/D offers identical functionality but with CMOS input thresholds instead of TTL. MC74VHC1GT50DFT1G provides the same electrical performance in an SC-88A package. Cross-reference package dimensions and pinout orientations before substitution.
