PCA9555PW - Brand New NXP Semiconductors IC Chips
-
Description
The PCA9555PW is a 24-pin CMOS device that provides 16 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C/SMBus applications. It is developed to enhance the Philips family of IC I/O expanders. The PCA9555PW offers several improvements compared to its predecessors, including higher drive capability, 5 V I/O tolerance, lower supply current, individual I/O configuration, and smaller packaging. This makes it an ideal solution for adding additional I/O to ACPI power switches, sensors, pushbuttons, LEDs, fans, and more.
