PCA9539R port equivalent, 16-bit i2c and smbus low power i/o port.
* 16-bit I2C-bus GPIO with interrupt and reset
* Operating power supply voltage range of 2.3 V to 5.5 V (3.0 V to 5.5 V
for PCA9539PW/Q900 and PCA9539RPW/Q900)
and was developed to enhance the NXP Semiconductors family of I2C-bus I/O expanders. I/O expanders provide a simple solu.
The PCA9539; PCA9539R is a 24-pin CMOS device that provides 16 bits of General Purpose parallel Input/Output (GPIO) expansion with interrupt and reset for I2C-bus/SMBus applications and was developed to enhance the NXP Semiconductors family of I2C-bu.
