The PCF8574ATS/3,118 is an 8-bit remote I/O expander from NXP Semiconductors that utilizes a two-wire bidirectional I2C-bus interface. It operates over a supply voltage range of 2.5 V to 6 V and supports a 100 kHz I2C-bus 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. An active LOW open-drain interrupt output is included, which is activated when any input state differs from its corresponding input port register state.
The PCF8574ATS/3,118 is available in a 20-SSOP package and is designed for surface mount applications. It operates within a temperature range of -40°C to 85°C. The device also offers low standby current consumption of 2.5 µA typical.
Applications for this I/O expander include LED signs and displays, servers, keypads, industrial control, and mobile devices.
