1 8UNIT SOURCE TYPE DARLINGTON TRANSISTOR ARRAY WITH CLAMP DIODE DESCRIPTION is eightcircuit outputsourcing darlington transistor array. The circuits are made of PNP and NPN transistors. This semiconductor integrated circuit performs high current driving with extremely low inputcurrent supply. PIN CONFIGURATION IN 8 O IN 7 O FEATURES High breakdown voltage (BCEO > ) Highcurrent driving (Io() = ) With clamping diodes Driving available with PMOS IC output of 6 ~ 6 or with TTL output Output currentsourcing type IN IN IN IN6 IN7 IN8 s O O O O6 O7 O8 GND APPLICATIONS Drives of relays, printers, LEDs, fluorescent display tubes and lamps, and interfaces between MOSbipolar logic systems and relays, solenoids, or small motors FUNCTION The each have eight circuits, which are made of input inverters and currentsourcing outputs. The outputs are made of PNP transistors and NPN Darlington transistors. The PNP transistor base current is constant. A clamping diode is provided between each output and GND. S and GND are used commonly among the eight circuits. The inputs have resistance of kω, and voltage of up to is applicable. Output current is imum. Supply voltage S is imum.
