10. Internal Logic Signal Select Output Pin
*: Each internal circuit resistance varies by r30%.
Both the TH-OUT and LOGIC OUT circuits have the same open-drain circuit as the ORT circuit.
If their output pins are pulled up with a resistor to the supply voltage, their levels become low (internally on) at
reset and high (internally Hi-Z) during normal operation (at non-reset).
It is not necessary to connect a pull-up resistor when choosing ANALOG output mode ( terminal :OPEN)
Reset Circuit (ORT)
This circuit has an open-drain output. If the output is
pulled up with a resistor to the supply voltage, its
level becomes low (internally on) at reset and high
(internally Hi-Z) during normal operation (at a
non-reset).
