74LCXZ16244MEA

Overview

The onsemi 74LCXZ16244MEA is a 16-bit buffer and line driver belonging to the LCXZ logic family. It operates with a supply voltage range of 1.65V to 3.6V and features 5.5V-tolerant inputs, allowing safe interfacing with 5V systems while powered by lower voltages. The device utilizes an advanced silicon-gate CMOS technology designed for low power consumption and high-speed operation. It is housed in a VQFN-56 package, suitable for surface-mount applications requiring compact footprints and robust performance in portable electronics.

Feature Summary

• Provides 5.5V tolerant input levels compatible with mixed-voltage environments
• Utilizes advanced CMOS technology for low power dissipation
• Supports high-speed data transmission with controlled switching characteristics

Applications

• Portable consumer electronics requiring low voltage operation
• Mixed-voltage signal buffering between 3.3V and 5V domains
• High-density board designs utilizing small outline packages

Procurement Notes

Verify the specific suffix 'MEA' against official onsemi documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with design-in requirements regarding input tolerance and operating temperature ranges before finalizing procurement decisions.

Selection Notes

Select this component when designing systems that require driving 16-bit buses across different voltage domains. The 5.5V tolerance eliminates the need for level shifters when interfacing with legacy 5V peripherals. Consider the VQFN-56 package constraints for thermal management and PCB layout space.

Part Context

This part belongs to the LCXZ family, which combines the speed of LVC logic with the extended voltage tolerance of LVX devices. It serves as a bridge component in hybrid digital systems, enabling seamless communication between modern low-voltage processors and older 5V interface standards without additional translation circuitry.

Replacement Considerations

Consult onsemi's official cross-reference guides for verified equivalents. Generic replacements may lack the specific 5.5V input tolerance or package dimensions required for direct substitution.
