PCA9535BS,118

接口-I/O扩展器 I2C/SMBUS 16BIT GPIO

16-bit I2C-bus and SMBus, low power I/O port with interrupt

General description PCA9535BS,118

The PCA9535BS,118 PCA9535 and PCA9535C are 24-pin CMOS devices that provide 16 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C-bus/SMBus applications and was developed to enhance the NXP Semiconductors family of I2C-bus I/O expanders. The improvements 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, push buttons, LEDs, fans, etc.
