Connect to VSS

Connect to VDD

Connect to VSS

Connect directly to VSS or pull down. For the pull-down

connection, use of a resistor whose resistance is between 470

Ω and 10 kΩ is recommended.

Remark Because the circuit type numbers are standardized among the 78K Series products, they are not

sequential in some models (i.e., some circuits are not provided).
