74LCX126SJX

Overview

The onsemi 74LCX126SJX is a low-voltage quad buffer featuring five-volt tolerant inputs and outputs. It operates within a supply voltage range of 2.0V to 3.6V, supporting high-speed data transmission with propagation delays as low as 5.2ns at 3.3V. The device provides symmetrical output drive currents of 24mA for both high and low states, ensuring robust signal integrity in digital logic applications.

Feature Summary

• Provides four independent non-inverting buffer channels for signal conditioning
• Features five-volt tolerant inputs allowing safe interfacing between different voltage domains
• Offers symmetrical 24mA output drive capability for reliable load driving

Applications

• High-speed data bus buffering in portable electronic devices
• Level shifting between low-voltage logic families and 5V tolerant systems
• Clock distribution networks requiring precise timing control

Procurement Notes

Verify the specific suffix SJX against official datasheets to confirm package type and lead-free status. Ensure compatibility with target operating temperatures ranging from -40°C to +85°C. Confirm RoHS compliance requirements match project specifications before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring low-voltage operation with 5V tolerance. Consider the 14-SOP package constraints for PCB layout. Evaluate power consumption needs given the static current characteristics typical of the LCX series for optimal system efficiency.

Part Context

This part belongs to the 74LCX family of low-voltage CMOS logic devices. It serves as a buffer variant within the broader 74-series logic ecosystem, designed specifically for modern low-power applications where voltage translation and signal buffering are critical requirements.

Replacement Considerations

Check for direct pin-compatible alternatives such as the 74LVC126 or similar quad buffers from other manufacturers if supply constraints exist. Verify that replacement parts maintain the same 5V tolerance and output drive capabilities.
