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).
