PCAL6534 expander equivalent, ultra low-voltage translating 34-bit fm+ i2c-bus/smbus i/o expander.
* I2C-bus to parallel port expander
* 1 MHz Fast-mode Plus I2C-bus
* Operating power supply voltage range of 0.8 V to 3.6 V on the I2C-bus side
* Allows b.
for interfacing to sensors, push buttons, keypad, etc. In addition to providing a flexible set of GPIOs, it simplifies i.
The PCAL6534 is a 34-bit general purpose I/O expander that provides remote I/O expansion for most microcontroller families via the Fast-mode Plus (Fm+) I2C-bus interface. The ultra low-voltage interface allows for direct connection to a microcontroll.
