MC74VHC2G50MU1TCG

Overview

The MC74VHC2G50MU1TCG is a dual buffer and line driver manufactured by onsemi, belonging to the VHC logic series. It features two non-inverting channels with push-pull outputs in a TSSOP-8 package. The device operates within a supply voltage range of 2.0 V to 5.5 V. Key electrical parameters include a maximum static current of 1 µA and output drive capabilities of ±8 mA. Propagation delay is typically 4.5 ns at 5 V. It supports an operating temperature range from -55°C to +125°C and includes power-down protection on inputs.

Feature Summary

• Dual-channel non-inverting buffer configuration for signal buffering and level shifting
• CMOS technology providing high noise immunity and stable output performance
• Input structures designed to withstand voltages up to 7 V regardless of supply voltage
• Power-down protection provided on inputs to prevent excessive current draw

Applications

• Interface circuits between 5 V and 3 V logic domains
• Clock distribution and buffering in high-speed digital systems
• Memory data bus buffering and line driving applications

Procurement Notes

Verify the specific suffix 'TCG' against official onsemi documentation to confirm tape-and-reel packaging and lead-free status. Ensure the ordering part number matches the exact package variant required for your PCB footprint. Cross-reference the datasheet revision date to confirm technical specifications have not changed. Confirm RoHS compliance details directly from the manufacturer's material declaration.

Selection Notes

Select this component when a dual-channel buffer is required in a compact surface-mount package. The VHC series offers speed comparable to Bipolar Schottky TTL while maintaining low CMOS power dissipation. Consider the 2.0 V minimum supply voltage for compatibility with lower voltage logic families. Verify that the TSSOP-8 package dimensions fit within the available board space constraints.

Part Context

This component is part of the MC74VHC1G/2G/4G single/dual/quad buffer family. These devices are designed for applications requiring high-speed operation with low power consumption. The VHC series is pin-compatible with other standard logic families, facilitating design upgrades. It serves as a general-purpose buffer for digital signal integrity improvement.

Replacement Considerations

Check for direct substitutes such as MC74VHC2G50DFT2G or MC74VHC2G50MUT1G if package availability differs. Ensure any replacement maintains the same VHC logic family characteristics and TSSOP-8 footprint. Verify that alternative manufacturers offer equivalent propagation delays and output drive currents.
