74LCXH16244GX

Overview

The onsemi 74LCXH16244GX is a low-voltage 16-bit buffer and line driver belonging to the LCXH logic family. It features non-inverting outputs and operates within a supply voltage range of 1.65V to 3.6V. The device utilizes an industry-standard pinout compatible with other 74-series logic families, facilitating easy upgrades in mixed-voltage designs. It is housed in a TSSOP-48 surface-mount package, designed for high-density applications requiring robust signal buffering and line driving capabilities in portable and battery-powered systems.

Feature Summary

• Provides 16-bit buffering and line driving functionality with non-inverting logic
• Operates across a wide low-voltage supply range from 1.65V to 3.6V
• Features industry-standard pinouts for direct replacement of equivalent legacy devices

Applications

• Portable consumer electronics requiring low-power signal buffering
• Battery-operated equipment utilizing mixed-voltage logic interfaces
• High-density digital systems needing 16-bit data bus drivers

Procurement Notes

Verify the specific suffix 'GX' against the official onsemi datasheet to confirm the exact tape-and-reel packaging configuration and temperature grade. Ensure the ordering part number matches the required package variant, as suffixes often denote specific shipping or environmental qualifications distinct from the base device function.

Selection Notes

Select this component when designing systems that require 16-bit parallel data transmission at low voltages. It is suitable for replacing older 5V or 3.3V buffers in modern low-power architectures. Consider the TSSOP-48 package constraints regarding thermal dissipation and PCB space availability during layout planning.

Part Context

This device is part of the LCXH series, which extends the low-voltage performance of the standard LCX family. It serves as a bridge between different voltage domains in digital circuits, ensuring signal integrity while minimizing power consumption in compact electronic assemblies.

Replacement Considerations

Check for cross-reference parts such as the MC74LCXH16244 or equivalents from other manufacturers offering identical 16-bit low-voltage buffering in a TSSOP-48 package to ensure functional compatibility.
