PCA9555PW 16bit GPIO expander logic chip IC SMD TSSOP24

Description

PCA9555PW 16bit GPIO expander logic chip IC SMD TSSOP24

The PCA9555PW is a 16-bit I²C GPIO expander IC, ideal for adding more I/O to a microcontroller system. Here are its key specifications:

• Operating Voltage: 2.3V to 5.5V
• I²C Addressable: Supports I²C/SMBus interface with 4 configurable addresses
• GPIOs: 16 bidirectional I/O pins
• Interrupt Output: Notifies of input state changes
• Package: TSSOP-24 (SMD)
• Current Sink Capability: Up to 25mA per pin
• Operating Temperature: -40°C to +85°C
• Datasheet

This IC is commonly used in embedded applications where additional GPIOs are needed, such as in microcontrollers or processors with limited I/O pins.
