The PCA9538 is a 16-pin CMOS device that provides 8 bits of General Purpose parallelInput/Output (GPIO) expansion with interrupt and reset for I2C-bus/smbus applicationsand was developed to enhance the NXP Semiconductors family of I2C-bus I/O expanders.I/O expanders provide a simple solution when additional I/O is needed for ACPI powerswitches, sensors, push-buttons, LEDs, fans, etc.

PCA9519 是一個4 通道的I2C 總線/smbus 中繼器,可以實現將低電壓兩線串行總線接口的處理器與標準的I2C 總線或smbus I/O 相連。該中繼器在電平轉換中保持I2C 總線系統所有的模式和特點的同時,允許通過給數據總線(SDA)和時鐘總線(SCK)提供雙向緩沖區來擴展I2C 總線,從而使I2C 總線或smbus 在高電壓下最大容限電容為400PF。SDA 和SCL 引腳具有耐壓保護功能,當PCA9519 掉電時,均呈現出高阻抗特性。

The PCA9557 is a silicon CMOS circuit which provides parallel input/output expansion for smbus and I2C-bus applications. The PCA9557 consists of an 8-bit input port register, 8-bit output port register, and an I2C-bus/smbus interface. It has low current consumption and a high-impedance open-drain output pin, IO0. The system master can enable the PCA9557’s I/O as either input or output by writing to the configuration register. The system master can also invert the PCA9557 inputs by writing to the active HIGH polarity inversion register. Finally, the system master can reset the PCA9557 in the event of a time-out by asserting a LOW in the reset input. The power-on reset puts the registers in their default state and initializes the I2C-bus/smbus state machine. The RESET pin causes the same reset/initialization to occur without de-powering the part.

The Philips family of Multiplexers and Switches consists of bi-directional translating switches controlled via the I2C or smbus to fan out an upstream SCL/SDA pair to 2, 4 or 8 downstream channels of SCx/SDx pairs. The Multiplexers allow only one downstream channel to be selected at a time, while the Switches allow any individual downstream channel or combination of downstream channels to be selected, depending on the content of the programmable control register. Once one or several channels have been selected, the device acts as a wire, allowing the master on the upstream channel to send commands to devices on all the active downstream channels, and devices on the active downstream channels to communicate with each other and the master. External pull-up resistors are used to pull each individual channel up to the desired voltage level. Combined interrupt output and hardware reset input are device options that are featured.
