MC74VHC1GT50DT1G

Overview

The MC74VHC1GT50DT1G is a single-channel, non-inverting buffer and line driver from onsemi's VHC logic family. It utilizes high-speed CMOS technology to provide signal buffering with low power consumption. The device operates within a supply voltage range of 2 V to 5.5 V and features an SC-88A (SOT-353) five-pin surface-mount package. Key electrical characteristics include a maximum propagation delay of 4.5 ns at 5 V with a 50 pF load, output drive currents of ±8 mA, and a static current of 1 µA. It supports industrial temperature ranges from -55 °C to +125 °C.

Feature Summary

• High-speed CMOS performance with low power dissipation
• Single-channel non-inverting buffer configuration
• Wide operating voltage range supporting 2 V to 5.5 V
• Compact SC-88A surface-mount packaging

Applications

• Signal buffering in portable electronic devices
• Level shifting between different voltage domains
• Clock distribution networks
• Memory interface buffering

Procurement Notes

Verify the specific suffix 'DT1G' against official onsemi documentation to confirm pinout and electrical specifications, as variations exist within the VHC family. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the SC-88A package dimensions align with your PCB footprint design constraints.

Selection Notes

Select this component when a single-channel, non-inverting buffer is required for high-speed digital signals. The VHC series offers superior speed compared to standard HC logic while maintaining low power consumption. Consider the 2 V to 5.5 V operating range for compatibility with various system voltages. The SC-88A package is suitable for space-constrained designs requiring surface-mount assembly.

Part Context

This component belongs to the MC74VHC1GTxx series of single-gate buffers and drivers. It shares the same logical function as other members like the MC74VHC1GT50DFT2G but may differ in packaging or tape-and-reel specifications. The VHC family is designed for applications requiring fast switching speeds and low standby power, making it suitable for battery-operated and high-density digital systems.

Replacement Considerations

The MC74VHC1GT50DFT2G is a verified substitute with identical logical function and similar electrical characteristics. Verify package compatibility, as the DFT2G uses an SC-88A package similar to the DT1G. Ensure that any replacement maintains the required propagation delay and output drive current specifications for the application.
