No.7465-3/10

Internal Block Diagram

Sample Application Circuit

• The Co1 ground lead must be connected as close as possible to pin 1 on the hybrid IC.

• HC type CMOS levels are recommended as the input specifications for pins 6 to 9.

• In case of TTL input, connect a pull-up resistor. (Recommended value: 2kΩ)

• Excitation control input specifications
