PI4IOE5V9536
4-bit I2C-bus and SMBus low power I/O port
Features
Operation power supply voltage from 2.3V to 5.5V
4-bit I2C-bus GPIO with 5V tolerant I/Os
Polarity inversion register
Low current consumption
0Hz to 1MHz clock frequency
Noise filter on SCL/SDA inputs
Power-on reset
4 I/O pin which default to 4 inputs with 100kΩ pull-
up resistor

Offered in three different packages:SOIC-8,MSOP-8
and TDFN2x3-8
Pin Configuration
Description
The PI4IOE5V9536 provides 4 bits of General
Purpose parallel Input/Output (GPIO) expansion for I2C-
bus/ SMBus applications. It includes the features such as
higher driving capability, 5V tolerance, lower power
supply, individual I/O configuration, and smaller
packaging. It provides a simple solution when additional
I/O is needed for ACPI power switches, sensors, push
buttons, LEDs, fans, etc.
The PI4IOE5V9536 consists of a 4-bit registers to
configure the I/Os as either inputs or outputs, and a 4-bit
polarity registers to change the polarity of the input port
register data The data for each input or output is kept in
the corresponding Input port or Output port register. All
registers can be read by the system master.
