74LCXZ16244MEAX

Overview

The 74LCXZ16244MEAX is a low-voltage 16-bit buffer and line driver manufactured by onsemi. It belongs to the LCXZ logic family, designed for high-speed digital applications requiring robust signal integrity. The device features non-inverting logic functionality with three-state outputs, allowing multiple drivers to share a bus without contention. It operates within a wide supply voltage range, supporting both 1.8V and 3.3V systems while maintaining compatibility with 5V tolerant interfaces. The MEAX suffix indicates a specific tape-and-reel packaging configuration suitable for automated surface-mount assembly processes.

Feature Summary

• Provides 16-bit buffering and line driving capabilities for high-density data buses
• Features three-state outputs to facilitate bus sharing and system flexibility
• Supports mixed voltage operation with 5V-tolerant inputs and outputs
• Designed for low power consumption in portable and battery-operated devices

Applications

• High-speed data bus buffering in consumer electronics
• Memory interface buffering in computing systems
• Signal conditioning for communication protocols
• Portable equipment requiring low-voltage operation

Procurement Notes

Verify the complete part number including the MEAX suffix to ensure correct packaging. Confirm that the procurement source provides official datasheets from onsemi. Check for RoHS compliance documentation if required by your manufacturing standards. Ensure the supplier is an authorized distributor to guarantee component authenticity. Validate the lot date code against your production timeline requirements.

Selection Notes

Select this component when 16-bit parallel data handling is required. Choose it over standard LCX variants if enhanced performance or specific packaging is needed. Consider the 5V tolerance feature if interfacing with legacy 5V logic levels. Evaluate the package type availability for your PCB layout constraints. Compare propagation delay specifications against your system timing requirements.

Part Context

This component is part of onsemi's LCXZ series, which offers improved performance over standard LCX logic. The LCXZ family is optimized for low-voltage applications while maintaining compatibility with higher voltage systems. It serves as a bridge between modern low-power designs and existing 5V infrastructure. The 16-bit width makes it suitable for wide data paths common in memory and processor interfaces.

Replacement Considerations

Check for direct pin-to-pin replacements within the LCXZ family. Verify electrical characteristics match the original design requirements. Ensure the alternative package matches the footprint constraints. Confirm availability from authorized sources before switching suppliers.
