The Allegro Microsystems UDN2981A is an 8-channel bipolar source driver suitable for high-side switching applications. It is designed to interface between low-level logic and high-current loads such as relays, solenoids, lamps, and motors.
This device offers a continuous output current of 120mA per output under normal operating conditions (15V supply, +50°C ambient). It supports load supply voltages up to 50V and provides an output breakdown voltage of 50V. The inputs are compatible with TTL, DTL, PMOS, and CMOS logic systems and are activated by an active high input.
The UDN2981A is available in an 18-pin DIP (Dual In-line Package) with Through Hole mounting. The package features a copper lead frame for optimal power dissipation. These packages are lead (Pb) free with 100% matte-tin leadframe plating.
Key features include transient-protected outputs, input current limiting resistors, and separate logic and load grounds. The device operates over an ambient temperature range of -20°C to 85°C.
