Description: Remote 8-bit I/O expander
* I2C-bus to parallel port expander
* 400 kHz I2C-bus interface (Fast-mode I2C-bus)
* Operating supply voltage 2.3 V to 5.5 V with 5.5 V tolerant I/Os held to.
and the latched output ports have 25 mA high current sink drive capability for directly driving LEDs.
The PCA8574 and PC.
The PCA8574/74A 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, 400 kHz I2C-bus interface, three hardware address in.
