PCF8574APWR Description

Short technical summary and product information.

The PCF8574APWR from Philips is an 8-bit general-purpose remote I/O expander that communicates via the I2C interface. This device is designed for 2.5V to 6V VCC operation, making it compatible with a wide range of microcontrollers.

 

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 outputs are latched and possess high-current drive capability, suitable for directly driving LEDs. The device also includes an open-drain interrupt output.

 

With an operating temperature range of -40°C to 85°C and a maximum frequency of 0.1 MHz, the PCF8574APWR is suitable for various embedded applications. It exhibits low standby-current consumption, typically 10µA maximum, and its latch-up performance exceeds 100 mA per JESD 78, Class II.

 

Available in multiple package types including VQFN, TVSOP, PDIP, SOIC, and TSSOP, this I/O expander offers flexibility for different board designs. Its compatibility with most microcontrollers and its robust performance characteristics make it a versatile component for expanding I/O capabilities in embedded systems.
