MC74VHC1G50DFT2G-Q

Overview

The MC74VHC1G50DFT2G-Q 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 CMOS-level input thresholds. The device provides an output current capability of ±8 mA at 3.0 V and exhibits a typical propagation delay of 3.5 ns at 5 V. It includes over-voltage tolerant inputs and outputs up to 5.5 V, supporting partial power-down protection via IOFF. The component is housed in a compact SC-88A (SOT-353) package with five pins.

Feature Summary

• Provides high-speed buffering for digital signals with low propagation delay characteristics.
• Features robust input and output structures that tolerate voltages up to 5.5 V regardless of supply level.
• Supports partial power-down mode to prevent excessive current draw during system standby states.

Applications

• Interface circuits connecting 5 V logic domains to 3 V logic domains
• Portable equipment requiring minimal footprint and low power consumption
• Battery-powered systems utilizing CMOS logic buffers

Procurement Notes

Verify the specific suffix 'Q' indicates automotive qualification and AEC-Q100 compliance when sourcing. Confirm the DF suffix corresponds to the SC-88A package variant required for your layout. Ensure the ordering code matches the exact tape and reel specifications needed for your assembly process.

Selection Notes

Select this component when a single-channel buffer with CMOS input thresholds is required. Choose the MC74VHC1GT50 variant if TTL-compatible input thresholds are necessary instead. Consider the SC-88A package for space-constrained designs where other VHC packages may not fit the board outline.

Part Context
