General Description

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 interconnections to a minimum, for example, in ACPI power switches, sensors, push buttons, LEDs and fan control.

Key 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 inputs.
Vhys = 0.10 × VCC (typical).
Noise filter on SCL and SDA inputs.
5 V tolerant I/Os.
16 I/O pins which power up configured in input state.
Open-drai.
