MAX3316ECAE+

Overview

The MAX3316ECAE+ is a dual-transmitter, dual-receiver RS-232-compatible transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +2.25V to +3.0V supply and utilizes a proprietary low-dropout transmitter output stage with a dual charge pump. The device supports data rates up to 460kbps and requires only four 0.1µF capacitors for operation. It features a 300µA operating supply current and is housed in a 16-pin SSOP package. The component is rated for an industrial temperature range of -40°C to +85°C.

Feature Summary

• Proprietary low-dropout transmitter output stage enables RS-232-compatible performance at low voltages
• Dual charge pump voltage converter generates required internal supplies using minimal external capacitance
• Guaranteed high-speed data transmission capability up to 460kbps under specified load conditions

Applications

• Palmtop Computers
• Hand-Held Instruments
• GPS Systems
• Cellular Phones

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature rating. Ensure compatibility with system power rails within the 2.25V to 3.0V range. Confirm that external capacitor values meet the minimum requirements for stable charge pump operation. Check for any regional distribution restrictions or discontinuation notices prior to finalizing procurement plans.

Selection Notes

Select this component when designing low-voltage serial communication interfaces requiring full-duplex RS-232 signaling. It is suitable for battery-powered portable devices where minimizing supply current is critical. Ensure the application environment stays within the specified -40°C to +85°C operating temperature range. Verify that the 16-pin SSOP footprint aligns with the target PCB layout constraints.

Part Context

This part belongs to the MAX3316–MAX3319 family of 2.5V RS-232 transceivers. The MAX3316 variant specifically provides two drivers and two receivers without AutoShutdown Plus functionality. It differs from the MAX3317/3318/3319 models which include advanced power-saving shutdown modes. The E suffix denotes the extended industrial temperature grade compared to the C suffix commercial grade.

Replacement Considerations

Direct functional substitutes within the same family include the MAX3316CAE+ for commercial temperature applications. For designs requiring shutdown control, consider the MAX3317ECAE+. Verify pinout compatibility and capacitor requirements when transitioning between these variants.
