The Texas Instruments PCF8574APWR is an 8-bit general-purpose remote I/O expander that communicates via the I2C interface. It is designed for operation with a VCC range of 2.5V to 5.5V, making it compatible with a wide array of microcontrollers.
This I/O expander features an 8-bit quasi-bidirectional I/O port that can function as either an input or an output without requiring a data-direction control signal. The outputs are latched and possess high-current drive capability, suitable for directly driving LEDs. At power-on, the I/Os default to a high state.
Key specifications include 8 I/Os, a maximum frequency of 0.1 MHz, and an operating temperature range of -40°C to 85°C. It also boasts a low standby-current consumption of 10 µA maximum. The device is available in various package types including VQFN, TVSOP, PDIP, SOIC, and TSSOP, with surface mount as the typical mounting type.
The PCF8574APWR is suitable for applications requiring additional I/O ports for microcontrollers, such as expanding control capabilities in embedded systems, interfacing with sensors, or driving multiple LEDs.
