Overview
The MAX7310ETE is an 8-bit parallel input/output port expander designed for SMBus and I2C-compatible applications. It integrates an input port register, output port register, polarity inversion register, configuration register, bus timeout register, and a serial interface. The device operates within a supply voltage range of 2.3V to 5.5V and supports a maximum clock frequency of 400kHz. It features low standby current of 1.7µA typical and provides 56 slave ID addresses. The component includes ESD protection and functions reliably across an operating temperature range from -40°C to +125°C.
Feature Summary
- Provides 8-bit parallel I/O expansion with configurable polarity inversion and bus timeout capabilities for lock-up-free operation.
- Features a 2-wire serial interface compatible with SMBus and I2C standards, supporting multiple slave addresses.
Applications
- Servers
- RAID Systems
- Industrial Control
- Medical Equipment
- Instrumentation and Test Measurement
Procurement Notes
Verify the specific suffix 'ETE' against official Analog Devices documentation to confirm package type and tape/reel specifications. Ensure compatibility with system voltage levels and interface protocols before integration. Check for RoHS compliance status and lead-free manufacturing details in the latest datasheet revision.
Selection Notes
Select this component when 8-bit I/O expansion is required with SMBus or I2C connectivity. Consider the wide operating temperature range and low standby current for power-sensitive designs. Verify that the 5V tolerant open-drain output on I/O0 meets the target circuit requirements.
Part Context
The MAX7310 belongs to the Maxim Integrated I/O expander family, offering compact solutions for adding digital inputs and outputs to microcontroller systems. It utilizes a thin QFN package to minimize board space while maintaining robust electrical performance for industrial and commercial environments.
Replacement Considerations
Review the MAX7311 for expanded 16-bit capability with interrupt support. Evaluate other members of the MAX73xx series for pin-compatible alternatives or enhanced feature sets depending on specific application needs.
