Product Summary

Low output-saturation voltage at high load current is provided by the UDN2596A sink driver IC. The device can be used as interface buffers between standard low-power digital logic(particularly MOS) and high-power loads such as relays, solenoids, stepping motors, and LED or incandescent displays. The eight saturated sink drivers in each device feature high-voltage, high-current open-collector outputs. Transient suppression clamp diodes and a minimum 35 V output sustaining voltage allow their use with many inductive loads. The saturated (non-Darlington) NPN output UDN2596A provides low collectoremittervoltage drops as well as improved turn-off times due to anactive pull-down function within the output predrive section. The UDN2596A is for use with output loads to 500 mA while the UDN2596A is for use with loads to 1 A. Adjacent outputs may be paralleled for higher load currents.
