PCA8574 PCA8574A 2 Remote 8-bit I/O expander for I C-bus with interrupt Rev. 3 3 June 2013 Product data sheet 1. General description The PCA8574/74A provides general-purpose remote I/O expansion via the two-wire 2 bidirectional I C-bus (serial clock (SCL), serial data (SDA)). 2 The devices consist of eight quasi-bidirectional ports, 400 kHz I C-bus interface, three hardware address inputs and interrupt output operating between 2.3 V and 5.5 V. The quasi-bidirectional port can be independently assigned as an input to monitor interrupt status or keypads, or as an output to activate indicator devices such as LEDs. The system master can read from the input port or write to the output port through a single register. The low current consumption of 4.5 A (typical, static) is great for mobile applications and the latched output ports have 25 mA high current sink drive capability for directly driving LEDs. The PCA8574 and PCA8574A are identical, except for the different fixed portion of the slave address. The three hardware address pins allow eight of each device to be on the 2 same I C-bus, so there can be up to 16 of these I/O expanders PCA8574/74A together on 2 the same I C-bus, supporting up to 128 I/Os (for example, 128 LEDs). The active LOW open-drain interrupt output (INT) can be connected to the interrupt logic of the microcontroller and is activated when any input state differs from its corresponding input port register state. It is used to indicate to the microcontroller that an input state has changed and the device needs to be interrogated without the microcontroller continuously 2 polling the input register via the I C-bus. The internal Power-On Reset (POR) initializes the I/Os as inputs with a weak internal pull-up 100 A current source. 2.
