Transistors - Bipolar (BJT) - Arrays

The ULN2003AS16-13 is a special type of transistor array that combines 16 NPN transistors with 13 open-collector output ports. It is manufactured using Advanced Semiconductor Inc’s special process for high scalability, high-density transistor grouping. This enables the ULN2003AS16-13 to be interconnected with existing and future devices without complicated wiring and interfacing. This makes it suitable for a variety of applications that require rugged high-current drivers with minimal heat dissipation.

The ULN2003AS16-13 has a wide working voltage range of 4.5v to 27v, which makes it ideal for use in many applications. Its low impedance output and open-collector output make it suitable for use in low voltage and high speed environments. It is also capable of driving high-current loads, up to 500mA at up to 5V. The ULN2003AS16-13 offers a range of features including built-in base termination, over-temperature protection, and surge protection, making it an excellent choice for applications requiring robust and reliable operation.

The ULN2003AS16-13 works on a simple principle. When an input voltage from 0 to 4.5V is applied to its base terminal, the NPN transistors conduct, allowing current to flow through the output ports and then from the outputs to ground. This creates an open-collector output, which can be used to drive loads. If the input voltage is increased to greater than 4.5V, the NPN transistors will switch off, allowing the output ports to assume a high impedance state. As the input voltage is decreased, the NPN transistors will turn on again and the output ports will go low impedance.

The ULN2003AS16-13 is a versatile transistor array. Its wide working voltage range, low impedance output, and open-collector outputs make it suitable for use in many applications. Its rugged construction, high-current output, and over-temperature protection make it an excellent choice for applications requiring robust and reliable operation. Its compact size and simple wiring make it easy to interface with existing and future devices. Its scalability and high-density integration make it ideal for large-scale projects such as those requiring the manipulation of large numbers of electrical signals.
