PI4IOE5V6416Q/PI4IOE5V6534Q I/O Expanders

Diodes’ automotive-compliant 16/34-bit I²C general-purpose I/O expanders feature built-in level-shifters

Diodes’ PI4IOE5V6416Q and PI4IOE5V6534Q are automotive-compliant, dual-power rail, general-purpose I/O expanders. They provide a simple and flexible solution when additional I/Os are needed, especially when interfacing between different logic levels. These devices provide 16-bits and 34-bits of I/O expansion, respectively. They can operate from 0.9 V/1.8 V to 5 V on the GPIO-port side and 0.8 V/1.65 V to 5.5 V on the I²C bus interface, allowing the devices to interface with next-generation microprocessors and microcontrollers on the SDA/SCL side where supply levels are reducing to conserve power. The PI4IOE5V6416Q is available in TSSOP-24 package, and the PI4IOE5V6534Q is available in W-QFN-46 package with wettable flanks.

Features

• Low operation power supply voltage from 0.9 V to 5.5 V
  • Supports the latest generation of low power supply microprocessors and microcontrollers
• Bidirectional voltage-level translation and GPIO expansion
  • Simplified interconnection between a processor running at one voltage level to I/O devices operating at a different (usually higher) voltage level
  • Saves PCB area and level shifter cost in design
• Intelligent I/O programming features:
  • Latchable inputs
  • Maskable interrupt
  • Programmable output drive strength
  • Programmable open-drain or push-pull outputs
  • Programmable pull-up/pull-down resistors
• Qualified to AEC-Q100 Grade 2
• Supports ambient temperature up to +105°C
• Wettable-flank QFN package for automotive applications
  • Supports automatic optical inspection (AOI) as demanded by many automotive manufacturers
