ULN2803APG DIP-18 ULN2803AG Darlington array driver chip

Eight NPN Darlington pairs: Consists of eight independent Darlington transistor pairs, each acting as a high-current switch.High-voltage outputs: Each channel can handle output voltages up to 50V.High output current: Each channel can sink up to 500mA continuously, with a peak rating of 600mA for some versions. Channels can be paralleled for even higher current capabilities.Integral clamp diodes: Includes built-in clamp diodes to suppress voltage spikes from inductive loads like relays or motors, protecting the chip and other components.Logic compatible inputs: Compatible with various logic levels, including TTL (Transistor-Transistor Logic) and 5V CMOS (Complementary Metal Oxide Semiconductor) inputs, facilitated by 2.7 k? base resistors.Convenient pinout: Inputs are typically located opposite the outputs, simplifying board layout.Wide operating temperature range: Operates reliably from -40°C to +85°C.
