I2C总线的EEPROM DIP开关方便系统管理 NXP 5-bit multiplexed / 1-bit latched 6-bit I2C-bus EEPROM PCA9559 I2C-bus EEPROM DIP switch for easy system management A simple way to implement open-drain buffer, jumperless configurations. The device provides four sets of potential outputs ― logic high, logic lows, outputs that reflect the part’s parallel inputs, or outputs configured by the I2C-bus. Key features The NXP PCA9559 is used to multiplex a default parallel input 4 Supports 5-bit, 2-to-1 multiplexing with an alternative set of inputs provided by the I2C-bus or 4 One channel w……
