The PCF8574ARGYR from Texas Instruments is an 8-bit general-purpose remote I/O expander that communicates via the I2C interface. Designed for 2.5V to 6V VCC operation, this device allows microcontrollers to expand their I/O capabilities efficiently.
Key features include an 8-bit quasi-bidirectional I/O port that can function as either input or output without requiring a data-direction control signal. The I/Os have latched outputs with high-current drive capability, suitable for directly driving LEDs. The device also includes an open-drain interrupt output, which is compatible with most microcontrollers. It operates at a maximum clock frequency of 100 kHz and has an operating temperature range of -40°C to 85°C.
This I/O expander is available in a 20-VQFN Exposed Pad package, suitable for surface mounting. Its low standby-current consumption of 10µA maximum and latch-up performance exceeding 100 mA per JESD 78, Class II, make it a robust choice for various embedded applications.
The PCF8574ARGYR is ideal for applications requiring additional digital I/O pins, such as controlling relays, reading sensors, or expanding user interfaces in embedded systems.
