MC74VHC1G126DTT1

Overview

The MC74VHC1G126DTT1G is a single-channel, non-inverting buffer and line driver from the onsemi VHC logic family. It utilizes high-speed silicon gate CMOS technology to provide signal buffering with low power dissipation. The device operates within a supply voltage range of 2.0 V to 5.5 V. It features three-state outputs controlled by an enable input, allowing for bus-oriented applications. The component is housed in a SC-74A (SOT-353) surface-mount package.

Feature Summary

• High-speed operation comparable to Bipolar Schottky TTL while maintaining CMOS low power characteristics
• Three-state output capability enables efficient bus management and signal isolation
• Wide operating voltage range supports compatibility with various digital logic systems
• Robust noise immunity and ESD protection ensure reliable performance in demanding environments

Applications

• Bus-oriented memory and signal switching applications
• Clock distribution and buffering circuits
• Signal level translation between different voltage domains
• Portable and battery-powered equipment requiring low power consumption

Procurement Notes

Verify the complete part number includes the suffix 'G' for lead-free compliance when ordering. Confirm the specific tape-and-reel quantity matches your production requirements. Ensure the SC-74A footprint aligns with your PCB design guidelines. Cross-reference the datasheet revision date to confirm current electrical specifications before finalizing procurement.

Selection Notes

Select this component for designs requiring a single-channel buffer with three-state control. It is suitable for replacing older bipolar logic families where lower power consumption is critical. Consider the VHC series for higher speed than standard HC logic. Verify that the input voltage levels are compatible with the driving source across the entire operating temperature range.

Part Context

This part belongs to the MC74VHC1G126 series of single non-inverting buffers. It shares functional compatibility with other members of the VHC family but differs in packaging and specific orderable suffixes. The device is designed for general-purpose digital applications requiring high speed and low power. It complements other single-gate logic devices in the same product line.

Replacement Considerations

Direct substitutes include MC74VHC1G126DFT1G and MC74VHC1G126DBVT1G, which offer identical functionality in alternative packages such as SC-88A or SC-70-5. Ensure pinout compatibility when swapping between different small-outline packages.
