Logic
Input Key
Note 1: The KEY input equivalent circuit is shown to the right.
1 channel and 2 channel is the separate action by 1Key pin and
2 key pin. When the control pin is open, it is outputted high level (about 1.4 V). Then the A channel input
signal is outputted. The change is carried out at low level.
Note 2: The specification means a value as measurement-input terminal connects to ground through a capacitor.
Note 3: ISO is a cross talk between A channel and B channel, SEP is a cross talk between 1 channel and 2
channel. The specification means a value as measurement-input termianl connects to ground through 10
k
resistor and capacitor.
Note 4: Power dissipation is 350 mW when mounted as recommended. Derate at 3.0 mW/
°
C for operation above
