MAX3385EEAP

Overview

The MAX3385EEAP+ is a high-speed, low-power RS-422/RS-485 transceiver manufactured by Analog Devices Inc. (Maxim Integrated). It features a single driver and receiver, supporting data rates up to 10 Mbps with a supply voltage range of +2.7V to +5.5V. The device includes ±15kV ESD protection on I/O pins and logic inputs, ensuring robust performance in harsh environments. Packaged in a thin SSOP-16, it operates within a temperature range of -40°C to +85°C. Key electrical parameters include a maximum propagation delay of 9ns and a shutdown current of less than 1µA, making it suitable for battery-powered applications requiring reliable serial communication.

Feature Summary

• Integrated ±15kV ESD protection on both signal and logic pins for enhanced durability
• Low power consumption with shutdown mode drawing less than 1µA
• High-speed data transmission capability up to 10 Mbps
• Compatible with standard RS-422 and RS-485 protocols

Applications

• Portable battery-operated equipment
• Industrial control systems
• Building automation networks
• Medical instrumentation

Procurement Notes

Verify the exact suffix against official datasheets, as variations may indicate different packaging or temperature grades. Confirm RoHS compliance status through manufacturer documentation. Check for obsolescence notices or lifecycle changes directly from Analog Devices. Ensure sourcing channels provide authentic components with traceable history to avoid counterfeit risks.

Selection Notes

Select this component when designing systems requiring high ESD immunity alongside low power consumption. Compare propagation delays and drive capabilities against alternative transceivers if signal integrity at extended distances is critical. Verify that the operating voltage range aligns with the system's power supply rails. Consider the thermal performance and package size constraints during PCB layout planning.

Part Context

This part belongs to the Maxim Integrated RS-422/RS-485 transceiver family, known for reliability in industrial communications. It complements other devices like the MAX3160 series but offers specific pinout and feature sets tailored for space-constrained designs. The EEAP suffix typically denotes a specific tape-and-reel packaging option for automated assembly processes.

Replacement Considerations

Direct pin-compatible replacements may include other Maxim RS-485 transceivers with similar ESD ratings and data rates. Verify functional equivalence regarding voltage levels and protocol support before substitution. Cross-reference with industry-standard alternatives if Maxim parts are unavailable, ensuring all electrical specifications meet or exceed original requirements.
