远程16位I2C和SMBus低功耗I / O扩展器,带有中断输出和配置寄存器 REMOTE 16-BIT I2C AND SMBus, LOW-POWER I/O EXPANDER WITH INTERRUPT OUTPUT AND CONFIGURATION REGISTERS
The is a remote 16-bit I²C and SMBus low-power I/O Expander with interrupt output and configuration registers. It provides general-purpose remote I/O expansion for most microcontroller families via the I²C interface serial clock SCL, serial data SDA. The PCA9535 consists of two 8-bit configuration input or output selection, input port, output port and polarity inversion active-high or active-low operation registers. At power on, the I/Os are configured as inputs. The system master can enable the I/Os as either inputs or outputs by writing to the I/O configuration bits. The data for each input or output is kept in the corresponding input or output port register. The polarity of the input port register can be inverted with the polarity inversion register. All registers can be read by the system master.
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
