General description
●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)).
●The 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.
●Features
●400 kHz I2C-bus interface
●2.3 V to 5.5 V operation with 5.5 V tolerant I/Os
●16-bit remote I/O pins that default to inputs at power-up
●Latched outputs with 25 mA sink capability for directly driving LEDs
●Total package sink capability of 400 mA
●Active LOW open-drain interrupt output
●8 programmable slave addresses using 3 address pins
●Readable device ID (manufacturer, device type, and revision)
●Low standby current (10µA max.)
●−40°C to +85°C operation
●ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per JESD22-A115, and 1000 V CDM per JESD22-C101
●Latch-up testing is done to JEDEC standard JESD78 which exceeds 100 mA
●Packages offered: SO24, SSOP24 (QSOP24), TSSOP24, HVQFN24, DHVQFN24
●Applications
