HQ: No Non-connection (NC)

FG: Other than the above pins, all are NC

(Since NC pins are not connected to the internal circuit, a potential can be applied to those pins.)

All control input pins: Pull-down resistor 100 k

Ω (typ.)

Note 1: If the FG pin number column indicates more than one pin, the indicated pins should be tied to each other at

a position as close to the pins as possible.

(The electrical characteristics of the relevant pins in this document refer to those when they are handled in

that way.)
