远程8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 8-BIT I2C AND SMBus LOW-POWER I/O EXPANDER WITH INTERRUPT OUTPUT AND CONFIGURATION REGISTERS
DESCRIPON/ORDERING INFORMATION
This 8-bit I/O expander for the two-line bidirectional bus I2C is designed for 2.3-V to 5.5-V VCC
operation. It provides general-purpose remote I/O expansion for most microcontroller families via the I2C interface [serial clock SCL, serial data SDA]. The PCA9534 consists of one 8-bit Configuration input or output selection, Input Port, Output Port, and Polarity Inversion active high or active low register. At power on, the I/Os are configured as inputs. However, 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 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.
