These devices 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 outputs provide low collectoremitter voltage drops as well as improved turn-off times due to an active pull-down function within the output predr...
