MC74VHCT126AMEL

Overview

The MC74VHCT126AMEL is a quad bus buffer and line driver manufactured by onsemi. It features four independent non-inverting buffers with three-state outputs, housed in a 14-pin SOIC package. The device operates within a supply voltage range of 4.5V to 5.5V, though it also supports operation at 3.3V. It provides high noise immunity and low power dissipation, designed for use in memory address drivers, clock drivers, and other bus-oriented systems.

Feature Summary

• Four independent non-inverting buffers with three-state outputs
• High noise immunity and low power dissipation characteristics
• Compatible with standard logic families including LSTTL loads

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented systems

Procurement Notes

Verify the specific suffix 'AMEL' against current manufacturer catalogs as distribution data may reference obsolete variants like 'ADR2'. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the 14-SOIC package dimensions match your PCB footprint design constraints before finalizing procurement.

Selection Notes

Select this component when a quad bus buffer with three-state control is required for 5V or 3.3V logic interfaces. It serves as a direct pin-compatible alternative to LS126 devices while offering CMOS performance benefits. Consider the 74VHCT series specifications for applications demanding high speed and low power consumption in bus driving scenarios.

Part Context

This part belongs to the 74VHCT logic family, which combines high-speed CMOS technology with TTL-compatible input levels. The 74VHCT126 specifically functions as a quad bus buffer. It is distinct from the HC and HCT families by its optimized performance characteristics for modern digital systems requiring efficient signal buffering across buses.
