1 General description
The PCA9537 is a 10-pin CMOS device that provides 4 bits of General Purpose parallel Input/Output (GPIO) expansion with interrupt and reset for I2C-bus/SMBus applications.
It was developed to enhance the NXP Semiconductors family of I2C-bus I/O expanders.
I/O expanders provide a simple solution when additional I/O is needed for ACPI power switches, sensors, push-buttons, LEDs, fans, etc.
The PCA9537 consists of a 4-bit Configuration register (input or output selection), 4-bit Input Port register, 4-bit Output Port register and a 4...
