MAX3316CAE+

Overview

The MAX3316CAE+ is a dual RS-232 transceiver from the MAX3316–MAX3319 family, designed for operation with a single +2.25V to +3.0V supply voltage. It features two drivers and two receivers providing full-duplex communication at guaranteed data rates up to 460kbps. The device utilizes a proprietary low-dropout transmitter output stage and an internal dual-charge pump requiring only four 0.1µF capacitors. Operating within the commercial temperature range of 0°C to +70°C, it consumes approximately 300µA during active transmission. The component is housed in a 16-pin SSOP package.

Feature Summary

• Proprietary low-dropout transmitter output stage enables RS-232-compatible performance down to 2.25V
• Internal dual-charge pump generates required voltages using only four external 0.1µF capacitors
• Guaranteed 460kbps data rate with worst-case loads of 3kΩ in parallel with 1000pF
• CMOS inputs feature Schmitt-trigger hysteresis for noise immunity

Applications

• Palmtop Computers
• Hand-Held Instruments
• Cellular Phones
• GPS Devices
• Handy Terminals

Procurement Notes

Verify that the ordering suffix 'AE' corresponds to the 16-pin SSOP package and the 'C' indicates the 0°C to +70°C commercial temperature range. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors before finalizing procurement specifications.

Selection Notes

Select this part when designing systems powered by a single 2.5V source requiring RS-232 connectivity without external voltage triplers. Ensure the application does not require the AutoShutdown Plus feature found on MAX3318/MAX3319 variants, as the MAX3316 lacks this specific power management capability.

Part Context

This component belongs to the MAX3316–MAX3319 series of low-voltage RS-232 transceivers manufactured by Maxim Integrated (now Analog Devices). The series differentiates models based on driver/receiver counts and power-saving features like AutoShutdown Plus. The MAX3316 specifically provides a standard 2-driver/2-receiver configuration optimized for space-constrained portable electronics.

Replacement Considerations

The MAX3316EAE+ serves as the industrial temperature variant (-40°C to +85°C) of this component. Other pin-compatible options within the same family include the MAX3317, which adds a shutdown control pin.
