PI4IOE5V9554ZHEX

I/o Expanders Overview

The PI4IOE5V9554ZHEX is an 8-bit I2C-bus and SMBus general-purpose input/output (GPIO) expander manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.3 V to 5.5 V and supports clock frequencies from 0 Hz to 400 kHz. The device features five-volt tolerant I/Os, an active-low interrupt output, and polarity inversion registers. It is housed in a TQFN-16 package with dimensions of 3.0 x 3.0 mm. Static characteristics include a typical operating current of 40 μA at 5.5 V and 10 μA at 2.3 V. ESD protection ratings are specified at 4 kV HBM and 1 kV CDM.

I/o Expanders Feature Summary

Provides 8 bits of GPIO expansion for I2C-bus and SMBus applications
Features 5V tolerant I/Os compatible with various logic levels
Includes an active-low open-drain interrupt output for state change detection
Supports hardware address selection via three pins for multi-device bus sharing

I/o Expanders Applications

ACPI power switches
Sensor interface connections
Push button scanning
LED control circuits
Fan speed monitoring

I/o Expanders Procurement Notes

Verify the specific ordering suffix ZHEX corresponds to the TQFN-16 tape and reel packaging configuration. Confirm that the A0-A2 address pin settings align with the required I2C bus topology to prevent address conflicts with other devices on the same serial line.

I/o Expanders Selection Notes

Select this component when an 8-bit parallel-to-serial conversion is required for low-speed peripheral control. Ensure the system design accommodates the open-drain nature of the interrupt output and provides appropriate pull-up resistors for the SCL and SDA lines to maintain signal integrity during communication.

I/o Expanders Part Context

This part belongs to the PI4IOE5V9554 family, which includes variants like the PI4IOE5V9554ALEX. The primary distinction between these variants lies in their fixed I2C base addresses, allowing up to sixteen devices to coexist on a single bus when mixing versions. The ZHEX suffix specifically denotes the thin fine-pitch quad flat no-lead package format.
