Overview
The MC74VHC1G126DFT2G is a single-channel, non-inverting buffer and line driver manufactured by onsemi. It belongs to the VHC logic series and operates within a supply voltage range of 2 V to 5.5 V. The device features three-state outputs with high-level output current of -8 mA and low-level output current of 8 mA. Static current is specified at 1 µA, while maximum power dissipation is 200 mW. Propagation delay is 11.5 ns. It functions in a temperature range from -55 °C to +125 °C and is housed in an SC-70 package.
Feature Summary
- Provides signal buffering and isolation through a single non-inverting channel
- Supports bus-oriented applications via three-state output control
- Operates across a wide industrial temperature range for robust performance
Applications
- Bus-oriented memory and signal switching
- Clock distribution and buffering
- High-speed data transmission lines
Procurement Notes
Verify the specific suffix DFT2G against official datasheets to confirm packaging type and tape-and-reel specifications. Ensure compatibility with existing design constraints regarding the SC-70 footprint and thermal management requirements. Confirm that the component meets all necessary regulatory standards for the intended deployment environment before finalizing procurement decisions.
Selection Notes
Select this component when a single-channel, non-inverting buffer with three-state capability is required for low-voltage digital systems. The VHC series offers high speed and low power consumption suitable for portable electronics. Consider the SC-70 package size if space-constrained designs are prioritized over higher drive currents found in larger packages.
Part Context
This part is part of the MC74VHC1G126 family of single-buffer devices. It serves as a fundamental building block for digital logic circuits requiring signal integrity maintenance. The device is designed to interface between different logic families or drive loads on shared buses where tri-state functionality prevents signal contention.
Replacement Considerations
Consult manufacturer cross-reference guides for direct pin-compatible alternatives. Verify electrical characteristics such as propagation delay and output current capabilities match system requirements when evaluating substitute components.
