*1: The MOD and CS0-CS2 pins should be used with fixed level input.
*2: Use particular caution in handling the SDA and SCL pins. These pins have no transistor protection against V
*3: When using the I/O expander function together with the D/A converter function, take care that D/A converter
Pin no.

D/A converter and I/O expander mode switching pin. *
Input “L” to operate as a D/A converter, “H” to operate as I/O expander and
D/A converter.
Lower 3 bits of the slave address setting pins. *
This allows up to eight MB88141 chips to be used on the same bus line.
8-bit D/A output with OP Amp. *
8-bit D/A output with OP Amp. *
In I/O expander operation, these pins function as parallel data input/output
pins.
Power supply pin for digital circuits and OP Amp.
GND pin for digital circuits and OP Amp.
Reference power supply pin for D/A converter (H). AO1 to AO4.
Reference power supply pin for D/A converter (L). AO1 to AO4.
