PCF8574A Remote 8-bit I/O expander

The PCF8574/74A 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, 100 kHz I2C-bus interface, three hardware address inputs and interrupt output operating between 2.5 V .

PCF8574A Features

* I2C-bus to parallel port expander

* 100 kHz I2C-bus interface (Standard-mode I2C-bus)

* Operating supply voltage 2.5 V to 6 V with non-overvoltage tolerant I/O held to VDD with 100 A current source

* 8-bit remote I/O pins that default to inputs at power-up

* Latched outputs di
