It provides general-purpose remote I\/O expansion for most microcontroller families via the I²C interface [serial clock (SCL), serial data (SDA)]. The PCA9555 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 register. The polarity of the input port register can be inverted with the Polarity Inversion register. The device outputs (latched) have high-current drive capability for directly driving LEDs. All registers can be read by the system master.\n\u003c\/div\u003e \n\u003cdiv\u003e \n \u003cul\u003e \n  \u003cli\u003eOpen-drain active-low interrupt (INT)\\ output\u003c\/li\u003e \n  \u003cli\u003eCompatible with most microcontrollers\u003c\/li\u003e \n  \u003cli\u003e400kHz Fast I²C bus\u003c\/li\u003e \n  \u003cli\u003eAddress by 3 hardware address pins for use of up to 8 devices\u003c\/li\u003e \n  \u003cli\u003ePolarity inversion register\u003c\/li\u003e \n  \u003cli\u003eLatched outputs with high-current drive capability for directly driving LEDs\u003c\/li\u003e \n  \u003cli\u003e1µA Maximum low standby-current consumption\u003c\/li\u003e \n  \u003cli\u003eGreen product and no Sb\/Br\u003c\/li\u003e \n \u003c\/ul\u003e \n\u003c\/div\u003e \n\u003cdiv\u003e \n \u003ch3\u003eApplications\u003c\/h3\u003e \n \u003cp\u003e Communications \u0026amp; Networking \u003c\/p\u003e \n\u003c\/div\u003e \n\u003ch3\u003eWarnings\u003c\/h3\u003e \n\u003cdiv\u003e\n Device has limited built-in ESD protection.
