MC74LCX244MN2TWG

Overview

The MC74LCX244MN2TWG is a low-voltage CMOS octal buffer with 5 V-tolerant inputs and outputs, manufactured by onsemi. It features non-inverting logic with three-state control, housed in a 20-QFN package measuring 2.5x4.5 mm. The device operates within a supply voltage range of 2.375 V to 3.8 V, supporting high-speed signal transmission with propagation delays as low as 6.3 ns at 2.7 V. Designed for surface-mount applications, it ensures reliable performance across industrial temperature ranges.

Feature Summary

• Provides eight non-inverting buffer channels with independent three-state output control
• Features 5 V-tolerant inputs and outputs for seamless interfacing between different voltage domains
• Utilizes low-voltage CMOS technology to minimize power consumption while maintaining high-speed performance

Applications

• Memory address buffering in portable electronic devices
• Clock distribution networks requiring level shifting
• Data bus drivers in battery-powered systems

Procurement Notes

Verify the exact suffix MN2TWG against official datasheets to confirm the specific tape-and-reel packaging and RoHS compliance status. Ensure the procurement source provides traceability documentation matching the manufacturer's specifications for quality assurance.

Selection Notes

Select this component when designing circuits that require driving loads between 3.3 V and 5 V systems without external level shifters. Consider the 20-QFN footprint for space-constrained PCB layouts and verify thermal dissipation requirements for high-density assemblies.

Part Context

This part belongs to the LCX series of low-voltage CMOS logic devices from onsemi. It serves as an octal buffer variant within the broader family of high-performance logic components designed for modern digital applications requiring low power and fast switching speeds.

Replacement Considerations

Check for direct pin-compatible substitutes such as other LCX244 variants from onsemi or equivalent parts from manufacturers like NXP or Texas Instruments, ensuring voltage tolerance and package dimensions match.
