MC74VHC1G50DFT2G

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 push-pull outputs capable of sourcing and sinking 8 mA at 3.0 V. The device utilizes CMOS level input thresholds and provides propagation delays of 6.4 ns maximum at 50 pF load for 3.0 V operation. It includes over-voltage tolerant inputs and outputs up to 5.5 V regardless of the supply voltage.

Feature Summary

• Provides protection against supply voltage mismatches through over-voltage tolerant input and output structures.
• Supports partial power down environments via IOFF functionality to prevent excessive leakage currents.
• Designed for high-speed signal buffering with advanced high-speed CMOS technology.

Applications

• Interfacing 5 V circuits to 3 V circuits
• Partial power down protection in battery backup systems
• Hot insertion applications

Procurement Notes

Verify that the specific ordering suffix matches the required package type and shipping quantity. Confirm RoHS compliance status and check for any recent Product Change Notifications (PCN) regarding manufacturing site or material changes. Ensure the component meets the required operating temperature range for the intended application environment.

Selection Notes

Select this part when a single-channel buffer with CMOS input thresholds is required. Compare against the MC74VHC1GT50 series if TTL input thresholds are necessary instead. Consider the SC-88A package dimensions for PCB layout constraints and verify that the 8 mA drive current meets the load requirements.

Part Context

This component belongs to the MC74VHC1G50/MC74VHC1GT50 family of advanced high-speed CMOS buffers manufactured by onsemi. The 'DFT' suffix indicates the SC-88A (SC-70-5/SOT-353) surface-mount package. The '2G' suffix typically denotes Pb-Free packaging and RoHS compliance.
