Overview
The MAX7315AEE is an 8-port I/O expander with LED intensity control, manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates on a supply voltage range of 2 V to 3.6 V and communicates via I2C, Serial, or SMBus interfaces with a maximum clock frequency of 400 kHz. The device features open-drain outputs capable of sourcing up to 50 mA per pin and includes interrupt output functionality. It is housed in a TQFN-16 package for surface mount installation and supports an operating temperature range from -40°C to +125°C.
Feature Summary
- Integrates eight general-purpose I/O ports with dedicated LED intensity control capabilities
- Supports standard I2C, Serial, and SMBus communication protocols
- Provides open-drain output configuration with high current drive capability
- Includes interrupt output feature for efficient event monitoring
Applications
- Portable electronic devices requiring expanded I/O and display control
- Industrial systems needing reliable I/O expansion in harsh environments
- Consumer electronics utilizing LED indicators and status displays
Procurement Notes
Verify the specific suffix 'AEE' against official Analog Devices documentation to confirm exact packaging and temperature grade specifications. Ensure compatibility with system voltage levels and interface requirements before procurement. Confirm RoHS compliance status through manufacturer datasheets. Validate availability through authorized distributors as supply conditions may vary.
Selection Notes
Select this component when an 8-port I/O expander with integrated LED dimming is required. Ensure the application operates within the 2 V to 3.6 V supply range. Verify that the I2C/SMBus interface matches the host controller's capabilities. Consider the TQFN-16 package constraints for PCB layout and thermal management during selection.
Part Context
The MAX7315AEE belongs to the MAX7315 series of I/O expanders designed by Maxim Integrated, now part of Analog Devices. This series focuses on providing versatile I/O expansion solutions with additional features like LED control for compact embedded applications. The AEE suffix typically denotes specific packaging and environmental ratings within the product line.
Replacement Considerations
Consult official Analog Devices substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully. Generic I/O expanders may not offer identical LED intensity control features.
