The PCF8574AT/3,512 is an 8-bit remote I/O expander designed for I2C-bus communication. It provides general-purpose I/O expansion via a two-wire bidirectional I2C-bus, operating at a 100 kHz standard-mode interface.
This device features eight quasi-bidirectional ports that can be independently assigned as inputs or outputs. The latched output ports can directly drive LEDs, and the total package sink capability is 80 mA. It operates within a supply voltage range of 2.5 V to 6 V and includes an active LOW open-drain interrupt output.
The PCF8574AT/3,512 is suitable for applications such as LED signs and displays, servers, keypads, and industrial control. It is available in a 16-SOIC package and supports surface mount.
Key electrical characteristics include an operating temperature range of -40°C to 85°C and a low standby current of 2.5 µA typical. The device also includes Power-On Reset (POR) functionality.
