MAX213EEAI+

Drivers, Receivers, Transceivers Overview

The MAX213EEAI+ is a single-supply RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a +5V supply and includes an integrated charge pump to generate the required ±10V levels, eliminating the need for external bipolar supplies. The device features four drivers and five receivers with full-duplex operation. It provides high electrostatic discharge protection of ±15kV via the Human Body Model. The component supports data rates up to 120kbps and functions within an industrial temperature range of -40°C to +85°C. It is housed in a 28-pin SSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry enables single +5V supply operation without requiring external bipolar voltage sources.
• High electrostatic discharge protection rated at ±15kV (Human Body Model) on driver outputs and receiver inputs.
• Low-power shutdown mode significantly reduces supply current consumption while maintaining functionality for specific receivers.
• Two dedicated receivers remain active during shutdown to monitor external activity.

• Hand-held equipment
• Portable diagnostics equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the exact ordering suffix against the manufacturer's official documentation to confirm pinout compatibility and electrical specifications. Confirm that the SSOP-28 package variant matches the target PCB footprint requirements. Ensure the component meets the necessary environmental standards for the intended deployment environment.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring robust ESD protection and low power consumption in portable applications. The inclusion of awake-in-shutdown receivers makes it suitable for monitoring tasks where minimal power draw is critical. Verify that the 120kbps data rate capability aligns with the system's communication speed requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX202E–MAX213E family of RS-232 transceivers. These devices are designed for harsh environments or applications involving frequent connection changes. The 'E' designation indicates enhanced ESD protection compared to standard versions. The family shares common architecture but varies in driver/receiver counts and control features.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX211EEWI+ is listed as a parameter equivalent alternative. Verify pin-to-pin compatibility and functional differences, particularly regarding the enable and shutdown control logic polarities which differ between these models.

Drivers, Receivers, Transceivers FAQ

How does the MAX213EEAI+ handle unused driver inputs?

Unused driver inputs have internal pull-up resistors to VCC. This forces the corresponding driver outputs low, preventing undefined states without requiring external components.

What is the behavior of the receivers during shutdown mode?

In shutdown mode, receivers R1 through R3 enter a high-impedance state. However, receivers R4 and R5 remain active to monitor external signals, allowing the system to detect activity while consuming minimal power.

What capacitor values are required for the charge pump?

The MAX213EEAI+ requires four external 0.1μF capacitors for the charge pump circuitry. Ceramic dielectrics are suggested for these capacitors.
