PCF8574P General Description
The PCF8574P is an 8-bit I/O expander IC (Integrated Circuit) designed by NXP Semiconductors. It is commonly used to add additional digital input/output (I/O) pins to a microcontroller or microprocessor using the I2C (Inter-Integrated Circuit) communication protocol. The "P" in the part number often indicates a plastic dual in-line package (PDIP).
Features
8-Bit I/O Expander: The PCF8574P provides eight additional I/O pins that can be used as either inputs or outputs.
I2C Communication: The device communicates with the microcontroller or microprocessor using the I2C serial communication protocol, allowing for multiple PCF8574P devices to be connected to the same bus.
Address Selectable: The IC has three hardware address pins, allowing for up to eight PCF8574P devices to share the same I2C bus, each with a unique address.
Input or Output Configuration: Each I/O pin can be individually configured as either a digital input or output.
Interrupt Function: The PCF8574P supports an interrupt output that can be used to inform the microcontroller when there is a change in the status of any of the I/O pins.
Low Standby Current: The device typically has low standby current, making it suitable for battery-powered applications.
Package Type: The "P" in the part number indicates a plastic dual in-line package (PDIP). Other package types may be available.
Application
I/O Expansion: Used to expand the number of available digital I/O pins on a microcontroller or microprocessor.
Keypad or Switch Inputs: Employed for reading inputs from keypads, switches, or other digital sensors.
LED or Relay Drivers: Used to drive LEDs or control relays based on the microcontroller's output.
Digital Displays: Applied in digital display applications where additional control lines are needed.
Sensor Interfaces: Used to interface with digital sensors requiring additional I/O lines.
