M74VHCT126ADTR2G

Overview

The M74VHCT126ADTR2G is a quad bus buffer manufactured by onsemi, belonging to the 74VHCT logic series. It features four independent buffers with three-state outputs and an active-low output enable input. The device operates within a supply voltage range of 2.0 V to 5.5 V and utilizes TSSOP-14 surface-mount packaging. It supports CMOS inputs while maintaining TTL-compatible thresholds, ensuring compatibility with standard logic families.

Feature Summary

• Provides four independent buffering channels for signal isolation and distribution
• Features three-state outputs controlled by a single active-low enable input
• Ensures system compatibility through TTL-compatible input switching thresholds

Applications

• High-speed data bus buffering in computing systems
• Signal driving for memory modules and peripheral interfaces
• Clock distribution networks requiring low skew and high fan-out

Procurement Notes

Verify the specific suffix 'A' against the manufacturer's current datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the TSSOP-14 package dimensions align with the PCB footprint. Confirm RoHS compliance status as per the latest regulatory documentation provided by onsemi before finalizing procurement.

Selection Notes

Select this component when designing circuits that require buffering between different voltage domains or increasing drive capability for long traces. The VHCT series is suitable for applications needing fast propagation delays and low power consumption. Verify that the operating temperature range meets the environmental conditions of the target application.

Part Context

This part belongs to the MC/M74VHCT126 family of quad bus buffers. It is functionally similar to other VHCT series devices but offers specific performance characteristics tailored for high-speed digital applications. The device is designed to interface with various logic families while providing robust signal integrity in complex digital systems.

Replacement Considerations

Compatible substitutes include MC74VHC126DTR2G and MC74VHCT125ADTRG. Verify pin-to-pin compatibility and ensure that the replacement part meets the same voltage and speed specifications required by the original design.
