PCA9671BS

Remote 16-bit I/O expander for Fm+ I2C-bus with reset; 1 MHz I2C-bus interface\nCompliant with the I2C-bus Fast-mode and Standard-mode\nSDA with 30 mA sink capability for 4000 pF buses\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 reset input\n64 programmable slave addresses using 3 address pins\nReadable device ID (manufacturer, device type, and revision)\nLow standby current\n-40 °C to +85 °C operation\nESD protection exceeds 2000 V HBM per JESD22-A114 and 1000 V CDM per JESD22-C101\nLatch-up testing is done to JEDEC standard JESD78 which exceeds 100 mA\nPackages offered: SO24, TSSOP24, HVQFN24, DHVQFN24\n;

The PCA9671 provides general purpose remote I/O expansion for most microcontroller families via the two-line bidirectional bus (I2C-bus) and is a part of the Fast-mode Plus (Fm+) family.\nThe PCA9671 is a drop in upgrade for the PCF8575 providing higher I2C-bus speeds (1 MHz versus 400 kHz) so that the output can support PWM dimming of LEDs, higher I2C-bus drive (30 mA versus 3 mA) so that many more devices can be on the bus without the need for bus buffers, higher total package sink capacity (400 mA versus 100 mA) that supports having all 25 mA LEDs on at the same time and more device addresses (64 versus 8) to allow many more devices on the bus without address conflicts.\nThe difference between the PCA9671 and the PCF8575 is that the interrupt output on the PCF8575 is replaced by a RESET input on the PCA9671.\nThe device consists of a 16-bit quasi-bidirectional port and an I2C-bus interface. The PCA9671 has a low current consumption and includes latched outputs with 25 mA high current drive capability for directly driving LEDs. The internal Power-On Reset (POR), hardware reset pin (RESET) or software reset sequence initializes the I/Os as inputs.\n
