PCF8574APWR Description

Short technical summary and product information.

The Texas Instruments PCF8574APWR is an 8-bit remote I/O expander that utilizes the I2C bus for communication. It is designed for operation with a VCC range of 2.5V to 6V and can function in temperatures from -40°C to 85°C.

 

This device features an 8-bit quasi-bidirectional I/O port (P0–P7) with latched outputs capable of high-current drive, making it suitable for directly driving LEDs. It includes an open-drain interrupt output and operates at a clock frequency of up to 100 kHz.

 

The PCF8574APWR is available in a 20-TSSOP package and is surface-mount compatible. Its low standby current consumption of 10 μA max and latch-up performance exceeding 100 mA per JESD 78, Class II, make it a versatile component for various microcontroller applications requiring expanded I/O capabilities.
