MAX3319EEAE

Overview

The MAX3319EEAE+T is a single-channel RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, designed for low-voltage applications. It operates within a supply voltage range of 2.25 V to 3.0 V, typically utilizing a 2.5 V source. The device supports data rates up to 460 kbps and features full-duplex communication with one driver and one receiver. Key electrical specifications include a maximum propagation delay of 0.175 µs and an operating supply current of 1 mA. It provides 15 kV ESD protection on all pins and includes an AutoShutdown Plus™ feature that reduces power consumption to 1 µA in shutdown mode. The component is housed in a 16-pin SSOP package.

Feature Summary

• AutoShutdown Plus™ technology enables ultra-low power consumption by automatically entering a 1 µA shutdown state when inputs are inactive or the device is disabled.
• Integrated dual charge pump generates required RS-232 voltage levels from a single low-voltage supply using only four 0.1 µF capacitors.
• Robust 15 kV human-body model ESD protection ensures reliability in high-static environments without external protection components.

Applications

• Portable battery-powered devices requiring minimal standby current
• Industrial handheld terminals and mobile data collection units
• Medical instrumentation with strict power constraints

Procurement Notes

Verify the suffix 'T' indicates reel packaging when sourcing. Confirm RoHS compliance status via official documentation. Ensure the specific grade matches environmental requirements. Cross-reference pinouts with application schematics. Validate supplier authenticity through authorized channels.

Selection Notes

Select this component for designs needing single-supply RS-232 connectivity with minimal capacitor count. Compare against MAX3316E if dual channels are required. Consider thermal performance within the SSOP-16 package. Verify voltage compatibility with target microcontrollers. Evaluate ESD requirements against operational environment standards.

Part Context

This part belongs to the MAX3316–MAX3319 family of 2.5V RS-232 transceivers. It shares core architecture with the MAX3318E but differs in channel configuration. The series emphasizes low-power operation and reduced external component counts compared to traditional ±5V transceivers.

Replacement Considerations

The MAX3318EEAE+T offers identical functionality but requires verification of channel count differences. The MAX3316EEAE+ serves as a dual-channel alternative within the same family. Check datasheet revisions for minor parameter updates before substitution.
