8-CHANNEL SOURCE DRIVER
Recommended applications requiring separate logic load grounds, load supply voltages load currents UDN2985A source driver used interface between standard low-power digital logic LEDs, relays, solenoids. outputs feature saturated transistors collector-emitter saturation voltages. UDN2985A driver with logic systems: TTL, Schottky TTL, DTL, CMOS. This device minimum output breakdown rating with minimum output sustaining voltage output switched active-high input level. Under normal operating conditions, this device source each eight outputs ambient temperature 75°C supply voltage incorporates input current-limiting resistors output transient-suppression diodes. UDN2985A source driver supplied 18-pin dual in-line package. inputs side package, output pins other, simplify printed wiring board layout.
