PI4IOE5V6416LEX

I/o Expanders Overview

The PI4IOE5V6416LEX is a low-voltage translating 16-bit I2C-bus I/O expander manufactured by Diodes Incorporated. It operates within a supply voltage range of 1.65 V to 5.5 V for both the I2C bus and GPIO ports, supporting standard mode (up to 100 kHz) and fast mode (up to 400 kHz) clock frequencies. The device features open-drain outputs with configurable drive strength, internal pull-up/pull-down resistances ranging from 50 kΩ to 150 kΩ, and an interrupt output pin. It provides ESD protection rated at 2 kV under human body model conditions and functions reliably across an operating temperature range of -40°C to +85°C.

I/o Expanders Feature Summary

• Supports bidirectional voltage translation between the I2C bus domain and GPIO port domain within the specified supply voltage limits.
• Provides sixteen individually configurable general-purpose input/output pins accessible via the I2C interface.
• Includes an interrupt output mechanism that signals state changes on configured input pins.

I/o Expanders Applications

• Embedded systems requiring expansion of microcontroller GPIO resources
• Low-voltage translating interfaces in portable electronic devices
• Industrial control systems utilizing I2C communication protocols

I/o Expanders Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging configuration. Confirm RoHS compliance status and lead-free definitions prior to procurement. Ensure the selected variant matches the required tape and reel specifications for automated assembly processes.

I/o Expanders Selection Notes

Select this component when designing circuits requiring 16-bit I/O expansion over an I2C bus with wide voltage compatibility. Evaluate the power supply requirements to ensure they fall within the 1.65 V to 5.5 V operational range. Consider the package availability and thermal characteristics relative to the target application environment.
