MAX3319EEAE+

Overview

The MAX3319EEAE+T is a single-channel RS-232 transceiver designed for low-voltage operation from +2.25V to +3.0V. It features AutoShutdown Plus technology, reducing supply current to 1µA when idle and 300µA during active transmission at data rates up to 460kbps. The device includes a dual charge pump requiring only four 0.1µF capacitors. It provides full-duplex communication with one driver and one receiver in a 16-pin SSOP package.

Feature Summary

• AutoShutdown Plus functionality automatically reduces power consumption by entering a low-power shutdown mode when the RS-232 cable is disconnected or peripheral transmitters remain inactive for over 30 seconds.
• Proprietary low-dropout transmitter output stage enables RS-232-compatible performance using a dual-charge pump with minimal external components.
• Logic-level READY output asserts high when the charge pump is regulating, indicating the device is ready to begin transmitting.

Applications

• Palmtop Computers
• Hand-Held Instruments
• Cellular Phones

Procurement Notes

Verify the component against official Analog Devices documentation to confirm pinout compatibility and electrical specifications. Ensure the ordering suffix matches the required temperature range and packaging format. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component for applications requiring single-supply RS-232 communication with strict power constraints. The MAX3319 is suitable for systems needing one transmitter and one receiver channel. Verify that the operating voltage falls within the +2.25V to +3.0V range and that the data rate requirements do not exceed 460kbps.

Part Context

This component belongs to the MAX3316–MAX3319 family of 2.5V RS-232 transceivers manufactured by Analog Devices (Maxim Integrated). The MAX3319 specifically offers a single-transmitter, single-receiver configuration, distinguishing it from the two-channel variants in the series while sharing identical power management and interface characteristics.

Replacement Considerations

Publicly confirmed substitutes include the MAX3316EAE+, MAX3317EAE+, and MAX3318EAE+. These parts share the same family characteristics but differ in the number of drivers and receivers available.
