These devices are suitable for interfacing between low-level logic and high-current loads such as relays, solenoids, lamps, motors, print hammers, and LEDs.
Features
Compatible with TTL, DTL, PMOS, and CMOS inputs
500 mA output source current capability
Transient-protected outputs
Output breakdown voltage up to 50 V
DIP or SOIC packaging
Applications
High-side switching applications
Interfacing between low-level logic and high-current loads
Driving relays, solenoids, lamps, motors, print hammers, and LEDs
