74LCX126BQX

Overview

The onsemi 74LCX126BQX is a quad buffer with non-inverting logic and three-state outputs, housed in a 14-DQFN (3x2.5) surface-mount package. It operates within a supply voltage range of 2V to 3.6V and supports an operating temperature from -40°C to +85°C. The device provides high drive capability with output currents of 24mA for both high and low states. It contains four independent 1-bit buffer elements, each with its own enable control, ensuring flexible signal routing in mixed-voltage systems.

Feature Summary

• Provides four independent non-inverting buffer channels with individual output enable controls
• Features three-state outputs that enter a high-impedance state when disabled
• Supports operation across a wide industrial temperature range

Applications

• Buffering signals in portable battery-powered equipment
• Driving bus lines in telecommunications infrastructure
• Signal isolation in industrial control systems
• Level shifting between 3.3V and 5V mixed-voltage environments

Procurement Notes

Verify the specific suffix 'BQX' to confirm the 14-DQFN package variant. Confirm RoHS compliance status and MSL rating requirements for your assembly process. Ensure the ordering quantity matches the manufacturer's standard packaging specifications. Cross-reference the datasheet revision date to ensure compatibility with current design constraints.

Selection Notes

Select this component when a quad buffer with independent tri-state control is required in a compact footprint. It is suitable for applications needing 24mA drive strength at low voltages. Consider the 14-DQFN package dimensions for PCB layout constraints. Verify input voltage tolerance if interfacing with higher voltage logic sources.

Part Context

This part belongs to the 74LCX series of low-voltage CMOS logic devices. It shares functional similarities with the 74LCX125 but differs in internal circuit configuration. The 74LCX family is designed for high-speed operations with low power consumption. It serves as a standard solution for buffering in modern electronic designs requiring small form factors.

Replacement Considerations

The 74LCX125BQX is a related component within the same series and package. Verify pinout compatibility and internal logic differences before substitution. Ensure electrical characteristics meet the specific application requirements.
