UDN2982A 8-Channel Source Drivers DIP IC

UDN2982A 8-Channel Source Drivers DIP IC

The UDN2982A-T is an 8-channel source driver IC designed for high-side switching applications. This integrated circuit enables low-level logic signals to control high-current loads, making it an excellent choice for interfacing microcontrollers or logic circuits with devices such as relays, solenoids, lamps, and motors. It features transient-protected outputs and can handle load supply voltages up to 50 V with peak output currents of up to 500 mA per channel. Compatible with TTL, DTL, PMOS, and CMOS logic families, the UDN2982A-T offers versatility in system design. Housed in an 18-pin Dual In-line Package (DIP), it is ideal for through-hole PCB designs.
