MC74VHC1G125DFT1

Overview

The MC74VHC1G125DFT1G is a single non-inverting 3-state buffer manufactured by onsemi in the VHC CMOS logic series. It operates within a supply voltage range of 2.0 V to 5.5 V and features high noise immunity with stable output. The device provides over-voltage tolerant inputs and outputs up to 5.5 V, allowing safe interfacing between 5 V and 3 V circuits. It supports partial power down protection via IOFF and delivers source/sink currents of 8 mA at 3.0 V. The component is available in SC-88A packages and complies with RoHS standards.

Feature Summary

• Single non-inverting 3-state buffer configuration
• Over-voltage tolerant inputs and outputs up to 5.5 V
• Supports partial power down protection
• High noise immunity with stable output

Applications

• Interfacing 5 V circuits to 3 V circuits

Procurement Notes

Verify the specific ordering suffix to confirm package type and shipping quantity. Confirm whether the -Q suffix is required for automotive or unique site control change requirements. Ensure the selected variant matches the desired tape and reel specifications. Check for Pb-free and halogen-free compliance status if environmental regulations apply to the assembly process.

Selection Notes

Select this component when a single-channel non-inverting buffer with 3-state output control is needed. Choose based on the required input threshold levels; standard VHC devices use CMOS thresholds while GT variants use TTL thresholds. Consider the SC-88A package for compact surface-mount designs. Verify that the operating temperature range meets the application's environmental constraints.

Part Context

This part belongs to the MC74VHC1G125 family of single buffers. It shares functional characteristics with other members like the MC74VHC1GT125, which differs primarily in input threshold levels. The family utilizes CMOS technology to achieve low static power consumption and high-speed operation suitable for portable and battery-powered electronics.
