MC74VHCT125ADTRG

Overview

The MC74VHCT125ADTRG is a quad buffer and line driver manufactured by onsemi, belonging to the 74VHCT logic series. It features four non-inverting buffers with three-state outputs housed in a 14-TSSOP package. The device operates within a supply voltage range of 2V to 5.5V, ensuring compatibility with standard CMOS logic levels while providing HCT-compatible input thresholds. It delivers an output current capability of 8mA for both high and low states. The component supports surface-mount installation and functions reliably across an extended industrial temperature range from -55°C to +125°C.

Feature Summary

• Provides four independent non-inverting buffer channels with individual three-state control for bus-oriented applications.
• Features HCT-compatible input thresholds allowing direct interfacing with TTL-driven systems despite CMOS construction.
• Supports wide supply voltage operation ranging from 2V to 5.5V for flexible power domain integration.

Applications

• Bus-oriented memory and address/data bus driving
• Clock buffering and distribution networks
• Signal level translation between different voltage domains

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm packaging type and tape dimensions. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary. Ensure the procurement channel is authorized to guarantee authenticity and traceability of the semiconductor components.

Selection Notes

Select this component when designing circuits requiring multiple buffered signals with tri-state capability on a shared bus architecture. The VHCT series offers superior switching speed compared to standard HC devices while maintaining HCT input compatibility. Consider the 14-TSSOP package constraints regarding thermal dissipation and PCB layout space during the schematic capture phase.

Part Context

This part belongs to the 74VHCT family of high-speed CMOS logic devices produced by onsemi. The VHCT series combines the performance benefits of VHC technology with the input compatibility of HCT standards. This specific model integrates four buffer gates into a single compact package, serving as a fundamental building block for digital signal routing and isolation in complex electronic systems.

Replacement Considerations

Check for pin-compatible alternatives such as the MC74HC125ADTR2G or MC74VHC125ADTR2G if HCT input thresholds are not strictly required. Verify that any substitute maintains the same 14-TSSOP footprint and electrical characteristics suitable for the target application environment.
