MAX7318AUG+

Overview

The MAX7318AUG+ is a 2-wire-interfaced, 16-bit I/O port expander in a 24-pin TSSOP package. It operates on a supply voltage of 2V to 5.5V with a maximum clock frequency of 400kHz. The device provides 16 configurable I/O pins that default to inputs upon power-up, featuring open-drain interrupt output and internal 100kΩ pullups. Standby current is typically 5.4µA at 3.3V. It supports hot insertion with high-impedance states up to 6V when powered down. Operating temperature range is -40°C to +125°C.

Feature Summary

Supports hot insertion with high-impedance protection on all pins when powered down
Configurable polarity inversion for input data via dedicated registers
Open-drain interrupt output activates on input state changes
Noise filters on SCL/SDA inputs suppress spikes less than 50ns

Applications

Servers
RAID Systems
Industrial Control
Medical Equipment
PLCs

Procurement Notes

Verify the suffix AUG corresponds to the 24-pin TSSOP package variant. Confirm the A grade indicates the extended -40°C to +125°C automotive temperature range. Ensure the datasheet revision matches the specific manufacturing lot requirements for your design integration.

Selection Notes

Select this component when 16 general-purpose I/O lines are required over an I2C/SMBus interface. The TSSOP package suits applications needing moderate pin density. Verify that the 400kHz bus speed and 5.5V overvoltage tolerance meet system signal levels. Consider the 5.4µA standby current for low-power designs.

Part Context

The MAX7318 series expands I/O capabilities for SMBus and I2C systems. The AUG suffix specifically denotes the Thin Shrink Small Outline Package (TSSOP) with 24 leads. This variant shares core functionality with SO and SSOP versions but offers different physical footprint dimensions for PCB layout constraints.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family if package availability is limited. Verify register compatibility before substituting with other I/O expanders.
