MC74VHC1G126DBVT1G

Overview

The MC74VHC1G126DBVT1G is a single-channel, non-inverting buffer and line driver from the 74VHC logic family. It operates within a supply voltage range of 2 V to 5.5 V. The device features a three-state output capable of sourcing -8 mA and sinking 8 mA. It utilizes an SC-74A (TSOT-23-5) surface-mount package. Key electrical characteristics include a static current of 1 µA and a maximum operating supply current of 50 mA.

Feature Summary

• Provides signal buffering and line driving capabilities with non-inverting logic functionality.
• Features three-state outputs to facilitate bus-oriented communication systems.
• Designed for low-power applications with minimal static current consumption.

Applications

• Bus-oriented communication systems
• Clock distribution circuits
• Memory module data buffering

Procurement Notes

Verify the specific suffix DBVT1G against the manufacturer's official datasheet to confirm the SC-74A package and tape-and-reel configuration. Ensure compatibility with the required 2 V to 5.5 V supply voltage range and check RoHS compliance status as documented in the product specifications before finalizing procurement.

Selection Notes

Select this component when a single-channel, non-inverting buffer with three-state control is required in a compact TSOT-23 footprint. It is suitable for designs needing operation across a wide voltage range from 2 V to 5.5 V. Consider the 8 mA drive capability and low static current for power-sensitive digital logic interfaces.

Part Context

This part belongs to the MC74VHC1GT126 series of single non-inverting buffers with three-state outputs manufactured by onsemi. The VHC logic family offers high-speed performance comparable to LS-TTL while maintaining CMOS low-power advantages. The DBVT1G designation specifically identifies the SC-74A package variant within this product line.

Replacement Considerations

Cross-reference with other MC74VHC1GT126 variants such as MC74VHC1GT126DFT1G or MC74VHC1GT126DFR2G if different package options like SOT-353 are acceptable. Verify pinout compatibility and electrical parameters match the original design requirements before substitution.

FAQ
