MAX3316EAE+

Overview

The MAX3316EAE+ is a dual RS-232 transceiver from the MAX3316–MAX3319 family, manufactured by Analog Devices / Maxim Integrated. It operates on a single +2.25V to +3.0V supply and utilizes a proprietary low-dropout transmitter output stage with a dual-charge pump. The device provides two drivers and two receivers for full-duplex communication at data rates up to 460kbps. It requires only four 0.1µF capacitors for operation. The component is housed in a 16-pin SSOP package and supports an operating temperature range of -40°C to +85°C.

Feature Summary

• Proprietary low-dropout transmitter output stage enables RS-232-compatible performance down to 2.25V
• Dual-charge pump voltage converter generates internal supplies using only four external capacitors
• Guaranteed 460kbps data rate with worst-case loads of 3kΩ in parallel with 1000pF

Applications

• Palmtop Computers
• Hand-Held Instruments
• GPS Systems

Procurement Notes

Verify the specific suffix 'EAE+' against official documentation to confirm the 16-pin SSOP package and industrial temperature range (-40°C to +85°C). Ensure compatibility with the required +2.25V to +3.0V power supply architecture. Confirm that the ordering information matches the exact part number variant to avoid discrepancies in pin configuration or electrical characteristics.

Selection Notes

Select this component for applications requiring RS-232 communication in low-voltage systems without the need for voltage triplers. The MAX3316EAE+ is suitable where space savings are critical due to its 16-pin SSOP footprint. It is appropriate for designs needing guaranteed high data rates up to 460kbps while maintaining compatibility with standard PC-to-PC communication software.

Part Context

The MAX3316EAE+ belongs to the MAX3316–MAX3319 series of 2.5V RS-232-compatible transceivers. This family shares common features such as the dual-charge pump and low-power operation. Specific variants within the series differ in driver/receiver counts and shutdown capabilities, but all maintain the core low-voltage RS-232 interface functionality.
