UDN2981A 8-Channel Source Driver IC 5–50V 500mA DIP-18

The UDN2981A is an 8-channel source driver designed for high-side switching applications and for interfacing low-level logic with high-current loads. The device is suitable for systems using 5V logic, including TTL, Schottky TTL, DTL, and 5V CMOS. It supports load supply voltages up to 50V and provides an output source-current capability of up to 500mA. The device integrates input current-limiting resistors and output transient-suppression diodes, with the outputs activated by an active-high input
