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 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
Applications
- Telematics
- ADAS
- Infotainment systems
