MAX3384ECWN+

Overview

The MAX3384ECWN+ is a low-power RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +3.0V to +5.5V supply and features two drivers and two receivers with a guaranteed data rate of 250kbps. The device incorporates a dual charge pump requiring only four small capacitors for operation. It provides enhanced ESD protection on all I/O pins, rated at ±15kV (Human Body Model), ±8kV (IEC Contact Discharge), and ±15kV (IEC Air-Gap Discharge). The component includes a shutdown mode that reduces supply current to less than 1µA. It is housed in an 18-pin SO package and is specified for the commercial temperature range of 0°C to +70°C.

Feature Summary

• Integrated dual charge pump enables true RS-232 performance from a single low-voltage supply without external inductors.
• High electrostatic discharge protection on transmitter outputs and receiver inputs ensures robustness against handling and assembly stresses.
• Low-power shutdown mode significantly reduces supply current to extend battery life in portable applications.
• Latchup-free design guarantees reliable operation under extreme static discharge conditions.

Applications

• Hand-held equipment
• Battery-powered peripherals
• Printers
• PDAs

Procurement Notes

Verify the specific ordering suffix 'ECWN+' corresponds to the required 18-pin SO package and the commercial temperature range (0°C to +70°C). Confirm RoHS compliance status through official manufacturer documentation or authorized distributors, as suffixes may indicate lead-free processing variations. Ensure the source document explicitly supports the '+'' designation for this specific part number before finalizing procurement specifications.

Selection Notes

Select this component when interfacing TTL/CMOS logic with RS-232 standards in systems powered by a single +3.0V to +5.5V rail. It is suitable for designs requiring minimal external components due to the integrated charge pump. Consider the 18-pin SO package constraints and the 0°C to +70°C operating range. Verify compatibility with specific logic families such as ACT, HCT, AC, HC, or CD4000 CMOS based on the system voltage requirements.

Part Context

The MAX3384E family consists of low-power, true RS-232 transceivers designed for 3V to 5.5V operation. Variants include the MAX3384ECAP and MAX3384EEAP in SSOP packages, covering commercial and extended temperature ranges. The MAX3384ECWN+ specifically utilizes an 18-pin SO package for the commercial temperature grade. All variants share the same core functionality, including dual drivers/receivers and high ESD protection capabilities.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official manufacturer resources for cross-reference information regarding alternative RS-232 transceivers with similar pinouts and electrical characteristics.
