MAX211CAI-T

Drivers, Receivers, Transceivers Overview

The MAX211CAI-T is a +5V RS-232 transceiver from the MAX200-MAX209/MAX211/MAX213 family, manufactured by Analog Devices Inc./Maxim Integrated. It features four drivers and five receivers in a 28-pin SSOP package. The device operates on a single +5V supply using an integrated charge pump to generate ±10V internally, requiring only four 0.1µF external capacitors. It supports data rates up to 120kbps with full duplex communication. The 'C' suffix indicates a commercial temperature range of 0°C to +70°C, while the 'I' suffix denotes industrial grade availability in other variants; however, this specific part number specifies the commercial range. Supply current is typically 11mA active and 1µA in shutdown mode.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump eliminates need for bipolar supplies
• Low-power shutdown mode reduces consumption to 1µA
• TTL/CMOS compatible inputs and outputs
• Compact 28-pin SSOP package saves board space

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the exact ordering suffix configuration against the manufacturer's official datasheet before procurement. Confirm that the 'C' suffix corresponds to the required commercial temperature range (0°C to +70°C) for your application environment. Ensure the SSOP-28 package footprint matches your PCB design constraints. Cross-reference the component status as active or obsolete through authorized distributor channels.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single +5V supply is available and board space is limited. The integrated charge pump simplifies design by removing external voltage converters. Compare pin compatibility with similar MAX200 series parts if alternative sourcing is needed. Verify that the 120kbps data rate meets system requirements. Consider the shutdown feature for power-sensitive applications requiring minimal standby current.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX200-MAX209/MAX211/MAX213 family of RS-232 transceivers. These devices share common architecture including integrated charge pumps and low-power shutdown modes. The MAX211 specifically offers four drivers and five receivers, distinguishing it from lower-channel variants like the MAX202. The family is designed for portable applications where power efficiency and size are critical constraints.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitutes include MAX211EWI+ and MAX211EEWI+. Verify pinout compatibility and electrical specifications before substitution. Check temperature range differences between commercial and extended industrial grades.
