MC74VHC1G50DFT1G

Overview

The MC74VHC1G50DFT1G is a single-channel non-inverting buffer manufactured by onsemi, belonging to the 74VHC logic family. It operates within a supply voltage range of 2.0 V to 5.5 V and utilizes advanced high-speed CMOS technology. The device features an SC-88A (SOT-353) surface-mount package with five pins. It provides push-pull outputs capable of sourcing and sinking 8 mA at 3.0 V. Key electrical characteristics include a typical propagation delay of 3.5 ns at 5 V and input/output over-voltage tolerance up to 5.5 V.

Feature Summary

• Advanced high-speed CMOS technology designed for low power consumption and fast switching speeds.
• Input and output structures provide protection against voltages up to 5.5 V regardless of supply voltage.
• IOFF feature supports partial power-down mode to prevent excessive current draw during standby.
• Capable of interfacing 5 V circuits to 3 V circuits due to wide operating voltage range.

Applications

• Interface between 5 V and 3 V logic circuits
• Clock buffering and distribution
• Signal level translation in portable devices

Procurement Notes

Verify the specific ordering suffix 'DFT1G' corresponds to the SC-88A package and tape & reel shipping configuration. Confirm that the component meets RoHS compliance requirements if applicable to your manufacturing standards. Ensure compatibility with existing PCB footprint dimensions for the SC-88A case outline before finalizing procurement orders.

Selection Notes

Select this component when a single-channel non-inverting buffer is required in a compact SC-88A package. It is suitable for applications needing 8 mA drive capability and operation across a 2.0 V to 5.5 V supply range. Consider the MC74VHC1GT50 variant if TTL-level input thresholds are preferred over standard CMOS thresholds.

Part Context

This part belongs to the MC74VHC1G50/MC74VHC1GT50 series of single-buffer logic ICs from onsemi. The 'MC74VHC1G50' designation indicates CMOS-level input thresholds, distinguishing it from the 'MC74VHC1GT50' which features TTL-level inputs. Both share identical output characteristics and packaging options.

Replacement Considerations

The MC74VHC1GT50DFT1G serves as a functional substitute if TTL input thresholds are acceptable instead of CMOS thresholds. Other packages within the same family, such as SC-74A or SOT-553, may require schematic and layout modifications due to pinout differences.
