Remote 16-bit I/O expander for I2C-bus with interrupt; 400 kHz I2C-bus interface\n2.3 V to 5.5 V operation with 5.5 V tolerant I/Os\n16-bit remote I/O pins that default to inputs at power-up\nLatched outputs with 25 mA sink capability for directly driving LEDs\nTotal package sink capability of 400 mA\nActive LOW open-drain interrupt output\n8 programmable slave addresses using 3 address pins\nReadable device ID (manufacturer, device type, and revision)\nLow standby current (10 uA max.)\n-40 Cel to +85 Cel operation\nESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per JESD22-A115, and 1000 V CDM per JESD22-C101\nLatch-up testing is done to JEDEC standard JESD78 which exceeds 100 mA\nPackages offered: SO24, SSOP24 (QSOP24), TSSOP24, HVQFN24, DHVQFN24\n;

The PCA8575 provides general purpose remote I/O expansion for most microcontroller families via the two-line bidirectional I2C-bus (serial clock (SCL), serial data (SDA)).\nThe device consists of a 16-bit quasi-bidirectional port and an I2C-bus interface. The PCA8575 has a low current consumption and includes latched outputs with high current drive capability for directly driving LEDs.\nThe PCA8575 also possesses an interrupt line (INT) which can be connected to the interrupt logic of the microcontroller. By sending an interrupt signal on this line, the remote I/O can inform the microcontroller if there is incoming data on its ports without having to communicate via the I2C-bus. The internal Power-On Reset (POR) initializes the I/Os as inputs.\n
