Product Description

The PI4IOE5V9536 provides 4 bits of General Purpose parallel Input/Output (GPIO) expansion for I 2Cbus/ SMBus applications. It includes features like 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 required for ACPI power switches, sensors, push buttons, LEDs, fans, etc. The PI4IOE5V9536 consists of 4-bit registers to configure the I/Os as either inputs or outputs, and 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.

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 pullup resistor
  • ESD protection (4KV HBM and 1KV CDM)
  • Offered in three different packages:SOIC-8,MSOP-8 and TDFN2x3-8
