MC74VHC1GT50DFT2

Overview

The MC74VHC1GT50DFT2G is a single-channel, non-inverting buffer from the onsemi VHC logic family. 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 circuits. It supports partial power-down protection via IOFF functionality and delivers source/sink currents of 8 mA at 3.0 V. Packaged in the SC-88A (SOT-353) format, it exhibits a typical propagation delay of 3.5 ns at 5 V.

Feature Summary

• Features TTL-level input thresholds for direct compatibility with standard digital logic families.
• Provides over-voltage tolerance on both inputs and outputs up to 5.5 V regardless of supply voltage.
• Supports partial power-down protection through dedicated IOFF circuitry.

Applications

• Interfacing 5 V logic circuits with 3 V logic systems
• High-speed signal buffering in portable electronic devices
• Level translation in battery-powered equipment

Procurement Notes

Verify that the ordering suffix matches the required package type and shipping quantity. Confirm RoHS compliance status and check for any specific automotive or industrial qualification requirements if applicable to the target application environment.

Selection Notes

Select this component when TTL-compatible input thresholds are required alongside high-speed performance. Ensure the design accommodates the specified operating temperature range and verify that the load capacitance aligns with the desired propagation delay specifications.

Part Context

This part belongs to the MC74VHC1G series of advanced high-speed CMOS buffers manufactured by onsemi. The 'T' designation specifically indicates TTL-level input thresholds, distinguishing it from the 'MC74VHC1G50' variant which utilizes CMOS-level thresholds.

Replacement Considerations

The MC74VHC1G50DFT2G serves as a functional alternative within the same family, differing primarily in its CMOS-level input threshold characteristics rather than electrical performance metrics.
