The PCF8574AT/3,518 from NXP Semiconductors is a general-purpose remote I/O expansion device utilizing a two-wire bidirectional I2C-bus interface. It provides eight quasi-bidirectional ports that can function as inputs or outputs, making it suitable for applications like LED signs, keypads, and industrial control.
This I/O expander operates within a supply voltage range of 2.5V to 6V and supports a 100 kHz I2C-bus interface. Key features include latched output ports that can directly drive LEDs, a total package sink capability of 80 mA, and an active LOW open-drain interrupt output. The device is designed for operation in temperatures ranging from -40°C to 85°C.
Packaged in a 16-SOIC format, the PCF8574AT/3,518 is designed for surface mounting. Its internal Power-On Reset (POR) initializes the I/Os as inputs with a weak internal pull-up. The device also boasts low standby current consumption of 2.5 µA typical, making it suitable for mobile applications.
