Product Summary

The pca9555pw is a 24-pin CMOS device. The pca9555pw provides 16 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C/SMBus applications and was developed to enhance the Philips family of IC I/O expanders. The improvements of the pca9555pw include higher drive capability, 5 V I/O tolerance, lower supply current, individual I/O configuration, and smaller packaging. I/O expanders provide a simple solution when additional I/O is needed for ACPI power switches, sensors, pushbuttons, LEDs, fans, etc. The pca9555pw consists of two 8-bit Configuration.
