Package Type: The "DIP-16" designation indicates that the ULN2003 is housed in a Dual Inline Package with 16 pins.
Darlington Transistor Pair: A Darlington pair is a configuration of two bipolar transistors that provide high current gain. The ULN2003 integrates seven such pairs, making it suitable for driving higher current loads.
Inputs and Outputs: Each Darlington pair in the ULN2003 has a dedicated input pin and a corresponding output pin. When a logic high signal is applied to the input, the corresponding output can sink current from the load.
Flyback Diodes: The ULN2003 is designed to handle inductive loads, and each output usually includes a built-in flyback diode (or freewheeling diode) to protect against voltage spikes generated by inductive loads.
Voltage Ratings: The ULN2003 is designed to operate with a wide range of supply voltages, typically in the range of 5V to 15V.
