74LVCH32244AEC/G557

Overview

The 74LVCH32244AEC/G557 is a low-voltage CMOS buffer and line driver manufactured by Nexperia, distributed under the NXP USA Inc. brand. It belongs to the LVCH logic series and features a 96-pin LFBGA surface-mount package. The device operates within a supply voltage range of 1.2 V to 3.6 V and supports an operating temperature range from -40°C to +85°C. This component is currently marked as obsolete with a lifetime status indicating it will be discontinued.

Feature Summary

• Provides buffering and line driving capabilities for digital signals
• Utilizes low-voltage CMOS technology for power efficiency
• Designed for surface-mount installation in compact electronic assemblies

Applications

• General-purpose signal buffering in consumer electronics
• Line driving applications requiring low-voltage operation
• Digital interface circuits within embedded systems

Procurement Notes

This component is officially classified as obsolete and has reached end-of-life status. The manufacturer has announced that production will cease, and the factory is not accepting new orders. Procurement should focus on verifying existing stock availability through authorized distributors or secondary market suppliers, as direct manufacturing supply is no longer active.

Selection Notes

Engineers selecting this part must account for its obsolete status when designing new products. While the LVCH series offers standard low-voltage performance, the specific 96-pin LFBGA package limits replacement options. Designers should evaluate alternative components with similar electrical characteristics and pin compatibility to ensure long-term supply chain stability for future production runs.

Part Context

This device is part of the broader 74LVCH family of low-voltage CMOS logic devices. These components are designed to bridge the gap between traditional 5V logic and modern low-voltage systems. The specific model integrates buffering functions into a high-density package suitable for complex printed circuit board layouts requiring multiple signal paths.
