MAX211EAI+T

Drivers, Receivers, Transceivers Overview

The MAX211EAI+T is a fully compliant RS-232 transceiver from the MAX200-MAX209/MAX211/MAX213 family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5V supply and includes an integrated charge pump to generate ±10V internal voltages, requiring only four external 0.1µF capacitors. The device features five receivers and four drivers, supporting data rates up to 120kbps with TTL/CMOS compatible inputs. It is housed in a 28-pin shrink small-outline (SSOP) package and supports an industrial 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 low-power shutdown mode that reduces supply current to typically 1µA while disabling charge pumps and transmitter outputs.
• Provides receiver enable control to place outputs in a high-impedance state for direct connection to three-state buses.

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the component designation against official manufacturer documentation to confirm the specific SSOP package variant and extended temperature rating. Ensure compatibility with system power requirements and interface standards before integration.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a full RS-232 interface with multiple drivers and receivers is required within a compact footprint. The integrated charge pump simplifies design by removing the need for external voltage inversion circuits, reducing overall bill of materials.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX200-MAX209/MAX211/MAX213 family of +5V RS-232 transceivers. While sharing core architecture with other members like the MAX200 or MAX213, it is distinguished by its specific configuration of four drivers and five receivers in a 28-pin SSOP package.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout and electrical specifications carefully if considering alternative RS-232 transceivers from other manufacturers.

Drivers, Receivers, Transceivers FAQ

What is the maximum data rate supported by the MAX211EAI+T?

The device supports data rates in excess of 120kbps when loaded in accordance with EIA/TIA-232E specifications.

How does the shutdown mode affect the charge pump?

In shutdown mode, the charge pumps are turned off, V+ is pulled down to VCC, and V- is pulled to ground, significantly reducing power consumption.

Are unused driver inputs required to be connected?

No, unused driver inputs can be left unconnected because 400kΩ pullup resistors to VCC are included on-chip, forcing the outputs low.
