PCA9535 Datasheet (nexperia) - Low-voltage 16-bit I2C and SMBus low-power I/O expander

PCA9535, Low-voltage 16-bit I2C and SMBus low-power I/O expander

The PCA9535 provides 16 bits of General Purpose Input/Output (GPIO) expansion for I²C-bus/SMBus applications.

It is designed for a wide voltage range of 2.3 V to 5.5 V with interrupt.

Nexperia GPIO expanders provide an elegant solution when additional IOs are needed while keeping the interconnection

PCA9535 Features

* I²C-bus to parallel port expander

* Operating power supply voltage range of 2.3 V to 5.5 V

* Ultra low standby current consumption:

* 1 µA (maximum)

* Schmitt-trigger action allows slow input transition and better switching noise immunity at the SCL and SDA
