MAX3384ECWN

Overview

The MAX3384ECWN is a dual RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, designed for full-duplex communication. It operates within a supply voltage range of 2.35V to 5.5V and supports data rates up to 250kbps. The device integrates two drivers and two receivers, featuring 15kV ESD protection on both I/O and logic pins. It consumes only 1µA in shutdown mode and utilizes internal charge pumps to eliminate the need for external capacitors. Packaged in an 18-SOIC format, it functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrates internal charge pumps to generate required RS-232 voltages without external components
• Provides robust 15kV ESD protection on all signal pins including inputs and outputs
• Features ultra-low power consumption with a dedicated shutdown mode reducing current to 1µA

Applications

• Portable equipment requiring RS-232 connectivity with limited power budgets
• Industrial control systems utilizing serial communication interfaces
• Modems and handheld terminals needing reliable full-duplex data transmission

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm package type and temperature grade. Ensure compatibility with system voltage levels before integration. Check for RoHS compliance status if environmental regulations apply. Confirm availability through authorized distributors as stock levels fluctuate. Validate pinout configurations against the latest datasheet revision to prevent design errors.

Selection Notes

Select this component when designing circuits that require dual-channel RS-232 communication without external boosting capacitors. It is suitable for applications demanding high ESD immunity and low standby power. Compare driver/receiver counts against interface requirements to ensure sufficient channels. Consider the 18-SOIC footprint constraints during PCB layout planning. Evaluate thermal performance within the specified 0°C to +70°C operational window.

Part Context

This part belongs to the Maxim Integrated MAX3384 family of RS-232 transceivers. It shares functional similarities with other devices in the series but differs in package configuration and specific electrical characteristics. The ECWN suffix denotes the 18-SOIC package variant. It serves as a solution for compact serial communication designs requiring integrated power management.

Replacement Considerations

Direct substitutes include the MAX3384ECWP+ in a TSSOP package or the MAX3384EUB+ in a µMAX package. Verify pin-to-pin compatibility and electrical specifications before substitution. Ensure the alternative part meets the same ESD protection and data rate requirements.
