Each channel consists of a Darlington pair (two cascaded NPN transistors) providing high current gain (>1000). Input logic compatible with 5V TTL\/CMOS drives the base of the first transistor. Built-in 50V clamp diodes from each output to common COM pin absorb inductive kickback when driving relays, solenoids, or stepper motors.<\/p>\n
