PCA9561 Quad 6-bit multiplexed I2C EEPROM DIP switch

PCA9561 Description

PCA9561 Quad 6-bit multiplexed I2C-bus EEPROM DIP switch Rev.4 * 6 November 2012 Product data sheet 1.General .
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.

PCA9561 Features

* 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 multiplexer DIP switch
* Four internal non-volatile registers
* Internal non-volatile registers programmable and readable v

PCA9561 Applications

* when used to replace DIP switches or jumpers, since the settings can be easily changed via I2C-bus/SMBus without having to power down the equipment to open the cabinet. The non-volatile memory retains the most current setting selected before the power is turned off. The PCA9561 typically resides bet
