1.1 MΩ is installed between GND usually.
Delay adjustment range of resistance: 650(kΩ) to 1.35(MΩ)
L: Sleep mode (Power-supply current becomes several
μA)
H: Usually mode
Terminal is open, Pull-down in GND
Low is input, 5pin(VOUT) output the low level
Set the low pulse width by value is longer 3
μs
Terminal open, pull-up in VDD
Sorcing 0 V.
Power-supply voltage reaches the value below the detection
voltage, low is output
Low level is input to
MR
terminal, low is output
Open drain output
Range pull-up resistance: 10(kΩ) to 100(kΩ)
Standard voltage (3.05 V typ) for AD/DA is output
Outside puts capacity (0.1
