74LCX126M

Overview

The onsemi 74LCX126M is a low-voltage quad buffer featuring five-volt tolerant inputs and outputs. It operates within a supply voltage range of 2.0 V to 3.6 V, supporting high-speed digital signal transmission in portable applications. The device provides three-state outputs for bus-oriented architectures, ensuring controlled data flow across multiple devices.

Feature Summary

• Provides four independent non-inverting buffers with three-state output control
• Features five-volt tolerant inputs allowing direct interfacing with 5V systems while operating at lower voltages
• Supports low-power CMOS technology suitable for battery-powered portable electronics

Applications

• Bus-oriented memory and address drivers
• Clock distribution circuits
• Data acquisition systems requiring level shifting between 3.3V and 5V domains

Procurement Notes

Verify the specific manufacturer datasheet revision and package marking codes before procurement. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure the ordering suffix matches the required tape-and-reel or tube packaging configuration for your assembly line.

Selection Notes

Select this component when designing systems requiring interface between 3.3V logic and 5V peripherals without external level shifters. Consider the propagation delay and output drive current specifications relative to your load capacitance requirements. Verify that the operating temperature range meets your environmental constraints.

Part Context

This part belongs to the 74LCX family of low-voltage CMOS logic devices manufactured by onsemi. It is functionally compatible with similar quad bus buffers from other manufacturers, such as Fairchild Semiconductor's 74LCX126 series, offering pin-to-pin interchangeability in standard SOIC-14 packages.
