74LCX16244GX

Overview

The onsemi 74LCX16244GX is a low-voltage 16-bit buffer and line driver featuring non-inverting logic with three-state outputs. Designed for high-performance applications, it operates within a supply voltage range of 2.3V to 3.6V. The device incorporates 5V tolerant inputs and outputs, allowing safe interfacing with 5V systems while powered by lower voltages. It supports live insertion and withdrawal, ensuring system stability during hot-swapping operations.

Feature Summary

• Provides sixteen non-inverting buffers with independent nibble control for flexible bus management
• Features 5V tolerant I/Os to ensure compatibility with mixed-voltage logic families
• Supports live insertion and withdrawal without causing system disruption or signal corruption

Applications

• Memory address drivers in high-density storage systems
• Clock distribution networks requiring precise timing and low noise
• Bus-oriented transmitter and receiver interfaces in communication modules

Procurement Notes

Verify the specific suffix 'GX' against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your region. Cross-reference the pinout diagram with your PCB layout to confirm alignment with the intended footprint before finalizing procurement orders.

Selection Notes

Select this component when designing systems that require 16-bit data buffering with mixed 3.3V and 5V logic levels. The 5V tolerance feature eliminates the need for additional level-shifting circuits. Consider the device's low static power consumption and high ESD protection ratings for robust operation in electrically noisy environments.

Part Context

This part belongs to the LCX family of low-voltage CMOS logic devices from onsemi. It serves as a critical interface component in digital systems, bridging gaps between different voltage domains. The 16-bit configuration allows for efficient parallel data handling, reducing board space compared to using multiple smaller buffers.

Replacement Considerations

The 74LCX16244G is a compatible alternative from the same manufacturer series. Verify pin compatibility and electrical characteristics before substitution. Other manufacturers may offer equivalent parts under different naming conventions, but functional verification is required.
