MAX213EAI+

Drivers, Receivers, Transceivers Overview

The MAX213EAI+ is a +5V RS-232 transceiver featuring four drivers and five receivers in a 28-pin SSOP package. It operates on a single +5V supply using an integrated charge pump to generate ±10V internal rails, requiring only four 0.1µF external capacitors. The device supports data rates up to 120kbps with full-duplex communication. Key electrical parameters include a typical power-supply current of 20mA, a shutdown current of 50µA, and a propagation delay of 40µs during shutdown mode. It functions within a temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry eliminates the need for bipolar ±12V supplies, enabling operation from a single +5V source.
• Includes two receivers (R4 and R5) that remain active during shutdown mode to monitor external activity while maintaining low power consumption.
• Provides TTL/CMOS compatible inputs with guaranteed receiver input thresholds tighter than EIA/TIA-232E specifications for improved noise margins.

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment
• Handheld devices
• Portable diagnostics equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the component matches the specific Analog Devices / Maxim Integrated MAX213EAI+ designation. Confirm the package type is SSOP-28 and the operating temperature grade is industrial (-40°C to +85°C). Ensure the datasheet revision aligns with the required specifications for your design implementation.

Drivers, Receivers, Transceivers Selection Notes

Select this part when a compact RS-232 interface is needed with minimal external components. The MAX213EAI+ is suitable for designs requiring ring indicator monitoring during low-power states. Compare against the MAX211 if fewer receivers are sufficient, or the MAX207 if a different pin count is preferred.

Drivers, Receivers, Transceivers Part Context

The MAX213EAI+ belongs to the MAX200-MAX209/MAX211/MAX213 family of +5V RS-232 transceivers. This series shares common architecture features such as integrated voltage conversion and low-power shutdown modes. The 'E' suffix denotes the extended industrial temperature range, while 'AI+' indicates the SSOP package and lead-free compliance.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitutes include the MAX213EAI and MAX213EAI-T. Verify pin compatibility and electrical characteristics before substitution. Other family members like the MAX211 offer similar functionality but with fewer receivers.
