MAX3384ECAP

Overview

The MAX3384ECAP is a low-power RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It features three drivers and two receivers, supporting full-duplex communication at data rates up to 125 kb/s. The device operates on a single supply voltage ranging from 3 V to 5.5 V, with a typical operating current of 0.1 mA in shutdown mode. It includes integrated charge pumps for generating positive and negative voltages required for RS-232 signaling. The component provides 15 kV ESD protection on all pins and is housed in a 20-pin TSSOP package.

Feature Summary

• Integrated charge pump eliminates the need for external capacitors
• High ESD protection rating on all signal pins
• Low power consumption with dedicated shutdown mode

Applications

• Portable equipment requiring RS-232 connectivity
• Battery-powered industrial control systems
• Modems and fax machines

Procurement Notes

Verify the manufacturer designation as Analog Devices Inc./Maxim Integrated when sourcing this component. Confirm the specific suffix 'ECAP' corresponds to the commercial temperature range and TSSOP-20 packaging. Check for end-of-life status or obsolescence notices prior to procurement planning.

Selection Notes

Select this part for applications requiring three drivers and two receivers within a compact footprint. Ensure the system voltage falls within the 3 V to 5.5 V range. Consider the 125 kb/s data rate limit when designing high-speed serial communication links.

Part Context

This component belongs to the MAX338x family of RS-232 transceivers designed for low-power applications. It shares functional similarities with other Maxim Integrated RS-232 parts but is distinguished by its specific driver/receiver count and package type.

Replacement Considerations

Direct substitutes may include other MAX338x variants with compatible pinouts. Verify electrical specifications and package dimensions before replacing.
