SN75064 ~ SN75067 current Darlington circuit diagram of a switch

  
SN75064 ~ SN75067 is a monolithic, high-voltage, high-current Darlington switch output termination
SN75064 ~ SN75067 current Darlington circuit diagram of a switch - schematic

has clamp diodes, suitable inductive loads. Each package of four Darlington pair can be used in parallel, so you can obtain further large current output. The chip output current up to 1.5A, rated power 2W, high voltage output, with output clamping diodes to the common emitter current absorption circuit. Wherein the input SN75064 / 75065 is compatible with TTL, DTL and 5V CMOS circuit; input SN75066 / 75067 is compatible with PMOS and high voltage CMOS circuit. By SN75066 for delay drive interface should use typical circuit is shown.
