CP82C55A Interface - I/O Expanders by Harris

Maximum current drawn from the power supply under specified operating conditions. Use this to estimate power dissipation and design your power supply and thermal management. Always check the datasheet for test conditions, as current can vary with voltage, frequency, and load.

Lists the product categories or classifications assigned to this component, such as connectors, capacitors, or modules. This helps in filtering and comparing similar parts. Review the categories to ensure the component fits your application and to find alternative parts in the same class.

Specifies the highest ambient temperature at which the component can operate reliably. Check this limit against your application's thermal environment to prevent overheating and ensure long-term stability. Always verify with the datasheet for derating curves.

Identifies the company that designed and produced the component. Buyers often filter by manufacturer to ensure brand reliability, quality standards, and supply chain consistency. Verify the manufacturer against the datasheet and official packaging to avoid counterfeit parts.

Describes the physical configuration of the component's leads or pads, such as through-hole, surface mount, or gull-wing. This affects PCB layout, soldering process, and mechanical fit. Confirm compatibility with your assembly method and footprint.

Indicates the specific product subcategories or classifications within the broader component family. Helps narrow down search results and identify the exact type of component needed for your design. Review the subcategory to ensure compatibility with your application.

Physical package or case type of the component, defining its dimensions, mounting style, and thermal characteristics. Common types include SMD, through-hole, BGA, and QFN. Choose the package that fits your PCB layout and assembly process. Verify the exact package code in the datasheet for footprint compatibility.

Thickness of the component, a critical dimension for PCB clearance, enclosure fit, and thermal performance. This measurement is especially important for capacitors, inductors, and connectors. Ensure the thickness meets your design constraints and does not interfere with adjacent components. Check the datasheet for tolerance and recommended mounting height.

The unique part number assigned by the original component manufacturer. Use this to cross-reference datasheets, verify specifications, and ensure the exact component matches your design requirements. Always confirm the number against the manufacturer's official documentation.
