| Parameter | Value |
|---|---|
Function Specifies the logical or operational function of the component, such as switching, amplification, or regulation. This attribute helps identify the device's role in a circuit. Verify the function against the datasheet to ensure it matches your application requirements. | 8-bit I2C/SMBus GPIO expander |
| Parameter | Value |
|---|---|
Number Of I/O Total number of input/output pins or channels available on the device. Determines connectivity and interface capability. Verify against your system requirements and datasheet to ensure sufficient I/O for your application. | 8 |
Manufacturer 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. | Texas Instruments |
Clock Frequency Operating frequency of the clock signal that drives the device. Determines processing speed and timing accuracy. Compare with your system's required clock rate and check the datasheet for maximum and typical values. | 400 kHz |
Package / Case 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. | 16-TSSOP |
Interface Specifies the communication protocol or interface type used by the component, such as I2C, SPI, UART, or USB. This determines how the device connects to a microcontroller or system. Verify compatibility with your host controller and bus voltage levels before design-in. | I2C / SMBus |
Replacement Role Specifies the functional role of a component when used as a direct replacement in a circuit. Helps engineers identify whether the part serves as a drop-in substitute, an alternative with minor differences, or a cross-reference. Verify against the original part's datasheet. | P2P review candidate |
Supply Voltage Specifies the nominal operating voltage that must be applied to the component for proper function. Verify this value against your system's power rail and the datasheet's absolute maximum ratings to ensure reliable operation and avoid damage. | 1.65 V to 5.5 V |
