ULN2002A Darlington Transistor Arrays DIP-16
This ULN2002A Darlington Transistor Arrays DIP-16 is a high-voltage, high-current driver featuring seven NPN Darlington pairs rated at 500 mA each, with common-cathode clamp diodes for inductive load suppression. Inputs are protected by series Zener diodes and resistors for compatibility with 14–25 V PMOS logic. Packaged in a standard 16-pin DIP, it operates over –20 °C to +70 °C and withstands up to 50 V on its outputs, making it ideal for robust relay, lamp, display, and line-driver applications.
