MC74VHC1G50DFT2

Overview

The MC74VHC1G50DFT2G is a single-channel, non-inverting buffer from the VHC logic family. It operates within a supply voltage range of 2.0 V to 5.5 V and features CMOS-level input thresholds. The device provides push-pull outputs capable of sourcing and sinking 8 mA at 3.0 V. Propagation delay is typically 3.5 ns at 5 V with a 15 pF load. Input and output structures are over-voltage tolerant up to 5.5 V regardless of the supply voltage. It is housed in an SC-88A (SOT-353) package.

Feature Summary

• Advanced high-speed CMOS technology designed for compact footprint applications
• Input and output structures provide protection against voltages up to 5.5 V independent of supply voltage
• IOFF feature supports partial power-down protection to prevent excessive current draw
• Pb-Free, Halogen/BFR-Free construction compliant with RoHS standards

Applications

• Interfacing 5 V circuits to 3 V circuits
• Portable equipment requiring small form factors
• Battery-powered systems utilizing low quiescent current

Procurement Notes

Verify the specific ordering suffix 'DFT2G' corresponds to the SC-88A package and tape & reel shipping configuration. Confirm that the 'G' suffix indicates Pb-Free status as defined in the manufacturer's ordering information table. Ensure the component matches the required CMOS input threshold variant rather than the TTL threshold GT50 series.

Selection Notes

Select this component when a single-channel non-inverting buffer with CMOS input thresholds is required. It is suitable for designs needing over-voltage tolerant I/Os without external protection components. Consider alternative packages like SOT-553 or UDFN6 if different mechanical constraints apply, provided the electrical characteristics remain consistent across the VHC family.

Part Context

This part belongs to the MC74VHC1G50/MC74VHC1GT50 advanced high-speed CMOS buffer series. The VHC family offers performance comparable to LS-TTL but with lower power consumption. The MC74VHC1G50 specifically utilizes CMOS level input thresholds, distinguishing it from the MC74VHC1GT50 which uses TTL level thresholds.

Replacement Considerations

Direct functional equivalents include other single-buffer devices within the 74VHC family. Verify pinout compatibility for SC-88A packages. Cross-reference with MC74VHC1G50 variants in different packages such as SC-74A or SOT-553 if mechanical changes are permissible.
