PCA9561 switch equivalent, quad 6-bit multiplexed i2c eeprom dip switch.
* Selection of non-volatile register_n as source to MUX_OUT pins via I2C-bus
* I2C-bus can override MUX_SELECT pin in selecting output source
* 6-bit 5-to-1 m.
when used to replace DIP switches or jumpers, since the settings can be easily changed via I2C-bus/SMBus without having .
The PCA9561 is a 20-pin CMOS device consisting of four 6-bit non-volatile EEPROM registers, six hardware pin inputs and a 6-bit multiplexed output. It is used for DIP switch-free or jumper-less system configuration and supports Mobile and Desktop VID.
