PI4IOE5V6416ALEX

I/o Expanders Overview

The PI4IOE5V6416ALEX 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 resistors, and an interrupt output pin. It is housed in a 24-pin TSSOP package and complies with RoHS directives.

I/o Expanders Feature Summary

• Provides voltage-level translation between the I2C bus domain and the GPIO port domain
• Supports configurable polarity inversion and interrupt masking for individual I/O lines
• Includes programmable internal pull-up and pull-down resistor networks

I/o Expanders Applications

• Embedded systems requiring remote GPIO expansion via I2C interface
• Low-voltage translating interfaces between different power domains
• Systems utilizing interrupt-driven input monitoring

I/o Expanders Procurement Notes

Verify the specific ordering suffix 'ALEX' corresponds to the 24-pin TSSOP package and tape/reel packaging format as defined in the manufacturer's ordering information. Confirm that the component meets required environmental compliance standards such as RoHS 3 and lead-free specifications before finalizing procurement orders.

I/o Expanders Selection Notes

Select this component when a 16-bit I/O expander with independent voltage domain translation is required. Ensure the application supports I2C communication protocols up to 400 kHz and operates within the specified -40°C to +85°C temperature range. Verify that the available I2C address configuration via the ADDR pin meets system addressing requirements.

I/o Expanders Part Context

This part belongs to the PI4IOE5V6416A series of low-voltage translating I/O expanders. The 'ALEX' suffix specifically denotes the 24-pin TSSOP package variant supplied in tape and reel format. It shares functional characteristics with other members of the family but differs in physical packaging and shipping configuration.

I/o Expanders Replacement Considerations

PI4IOE5V6416AZDEX serves as a package alternative in the same logical family, offering identical electrical functionality in a 24-contact TQFN package instead of the TSSOP form factor.
