Understanding the output configuration of a component is crucial for proper integration and operation within a circuit.
High Side - Output Current
The rated output current is the maximum load current that a power supply can provide at a specified ambient temperature. A power supply can never provide more current that it's rated output current unless there is a fault, such as short circuit at the load.
2.5A - Voltage - Supply (Vcc/Vdd)
Voltage - Supply (Vcc/Vdd) is a key parameter in electronic components that specifies the voltage level required for the proper operation of the device. It represents the power supply voltage that needs to be provided to the component for it to function correctly. This parameter is crucial as supplying the component with the correct voltage ensures that it operates within its specified limits and performance characteristics. It is typically expressed in volts (V) and is an essential consideration when designing and using electronic circuits to prevent damage and ensure reliable operation.
Not Required - Input Type
Input type in electronic components refers to the classification of the signal or data that a component can accept for processing or conversion. It indicates whether the input is analog, digital, or a specific format such as TTL or CMOS. Understanding input type is crucial for ensuring compatibility between different electronic devices and circuits, as it determines how signals are interpreted and interacted with.
Non-Inverting - Turn On Delay Time
Turn-on delay, td(on), is the time taken to charge the input capacitance of the device before drain current conduction can start.
1.5 ms - Switch Type
Based on their characteristics, there are basically three types of switches: Linear switches, tactile switches and clicky switches.
USB Switch - Ratio - Input:Output
The parameter "Ratio - Input:Output" in electronic components refers to the relationship between the input and output quantities of a device or system. It is a measure of how the input signal or energy is transformed or converted into the output signal or energy. This ratio is often expressed as a numerical value or percentage, indicating the efficiency or effectiveness of the component in converting the input to the desired output. A higher ratio typically signifies better performance or higher efficiency, while a lower ratio may indicate losses or inefficiencies in the conversion process. Understanding and optimizing the input-output ratio is crucial in designing and evaluating electronic components for various applications.

Engineers and designers often look at features such as operating voltage, speed, power consumption, and communication protocols to ensure compatibility and optimal performance.In summary, the "Features" parameter in electronic components describes the unique attributes and capabilities that differentiate one component from another, helping users make informed decisions when selecting components for their electronic designs.
Load Discharge, Status Flag - REACH SVHC
The parameter "REACH SVHC" in electronic components refers to the compliance with the Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) regulation regarding Substances of Very High Concern (SVHC). SVHCs are substances that may have serious effects on human health or the environment, and their use is regulated under REACH to ensure their safe handling and minimize their impact.Manufacturers of electronic components need to declare if their products contain any SVHCs above a certain threshold concentration and provide information on the safe use of these substances. This information allows customers to make informed decisions about the potential risks associated with using the components and take appropriate measures to mitigate any hazards.Ensuring compliance with REACH SVHC requirements is essential for electronics manufacturers to meet regulatory standards, protect human health and the environment, and maintain transparency in their supply chain. It also demonstrates a commitment to sustainability and responsible manufacturing practices in the electronics industry.

RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment.
ROHS3 Compliant - Lead Free
Lead Free is a term used to describe electronic components that do not contain lead as part of their composition. Lead is a toxic material that can have harmful effects on human health and the environment, so the electronics industry has been moving towards lead-free components to reduce these risks. Lead-free components are typically made using alternative materials such as silver, copper, and tin. Manufacturers must comply with regulations such as the Restriction of Hazardous Substances (RoHS) directive to ensure that their products are lead-free and environmentally friendly.
