STP16CPC26XTR Description
The STP16CPC26XTR is a 16-bit constant current LED sink driver that is monolithic and low voltage. A 16-bit shift register and data latches are included in the device, which transforms serial input data to parallel output format. In the output stage, sixteen controlled current generators deliver a constant current of 5 mA to 90 mA to drive LEDs. A resistor is used to control the current from the outside.
The OE pin can be used to adjust the LED brightness from 0% to 100%.
The 20 V driving capabilities of the STP16CPC26XTR allow users to connect additional LEDs in series to each current source.
The device's high 30 MHz clock frequency allows for high data rate transmission.
Overtemperature events are protected by the thermal shutdown (170 °C with roughly 15 °C hysteresis).
QSOP24, SO-24, TSSOP-24, and HTSSOP-24 are the four packages available for the STP16CPC26XTR (with exposed pad).

Engineers and designers use the voltage output specification to ensure compatibility and proper functioning of the component within the overall system.
20V - Topology
In the context of electronic components, "topology" refers to the arrangement or configuration of the components within a circuit or system. It defines how the components are connected to each other and how signals flow between them. The choice of topology can significantly impact the performance, efficiency, and functionality of the electronic system. Common topologies include series, parallel, star, mesh, and hybrid configurations, each with its own advantages and limitations. Designers carefully select the appropriate topology based on the specific requirements of the circuit to achieve the desired performance and functionality.
Shift Register - Output Current per Channel
Output Current per Channel is a specification commonly found in electronic components such as amplifiers, audio interfaces, and power supplies. It refers to the maximum amount of electrical current that can be delivered by each individual output channel of the component. This parameter is important because it determines the capacity of the component to drive connected devices or loads. A higher output current per channel means the component can deliver more power to connected devices, while a lower output current may limit the performance or functionality of the component in certain applications. It is crucial to consider the output current per channel when selecting electronic components to ensure they can meet the power requirements of the intended system or setup.

Exceeding this temperature can lead to thermal runaway, breakdown, or permanent damage to the device. Proper thermal management is essential to ensure the junction temperature remains within safe operating limits during device operation.
170°C - Voltage - Supply (Min)
Voltage - Supply (Min) is a parameter in electronic components that specifies the minimum voltage required for the component to operate within its specified performance range. This parameter indicates the lowest voltage level that can be safely applied to the component without causing malfunctions or damage. It is crucial to ensure that the supply voltage provided to the component is equal to or higher than the specified minimum voltage to guarantee proper functionality and reliability. Failure to meet this requirement may result in erratic behavior, reduced performance, or even permanent damage to the component.
3V - Multiplexed Display Capability
Multiplexed Display Capability refers to the ability of an electronic component or system to control multiple display elements using fewer input/output lines. This is achieved by rapidly switching between different displays or segments, allowing for efficient communication and reduced wiring complexity. In multiplexed systems, each display is activated sequentially, creating the illusion of simultaneous display to the user. This capability is commonly utilized in devices like LED matrices and LCD screens to enhance functionality while conserving space and resources.
NO - Display Mode
Display Mode in electronic components refers to the specific way in which information or data is presented on a display screen or panel. This parameter determines how the content is shown to the user, such as through text, graphics, images, or a combination of these elements.

No - RoHS Status
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.
