The PCA9674/74A provides general-purpose remote I/O expansion via the two-wire bidirectional I2C-bus (serial clock (SCL), serial data (SDA)). The devices consist of eight quasi-bidirectional ports, 1 MHz I2C-bus Fast-mode Plus (Fm+) family interface, with high speed data transfer it can support PWM dimming of LEDs, and higher I2C-bus drive 30 mA for more dev.
I2C-bus to parallel port expander
1 MHz I2C-bus interface (Fast-mode Plus I2C-bus)
SDA with 30 mA sink capability for 4000 pF buses
Operating supply voltage 2.3 V to 5.5 V with 5.5 V tolerant I/Os held to VDD with
100 A current source
8-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 200 mA
