MAX211EAI

Drivers, Receivers, Transceivers Overview

The MAX211EAI is a +5V RS-232 transceiver featuring four drivers and five receivers. It operates on a single +5V supply using an integrated dual charge pump, requiring only four 0.1µF external capacitors. The device supports data rates up to 120kbps with driver output slew rates of 30V/µs. Supply current is typically 14mA in active mode and reduces to 1µA in shutdown. It includes shutdown (SHDN) and enable (EN) control pins for power management and bus tri-stating. The EAI suffix indicates the SSOP-28 package variant.

Drivers, Receivers, Transceivers Feature Summary

• Integrated dual charge pump eliminates need for bipolar supplies
• Shutdown mode reduces power consumption significantly
• Enable control allows receiver outputs to be tri-stated
• TTL and CMOS compatible input thresholds

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the ordering suffix matches the required package type. The 'E' designation confirms industrial temperature range operation. Confirm the 'I' suffix corresponds to the shrink small-outline package. Ensure the datasheet revision aligns with design requirements. Check for RoHS compliance status if mandated by project specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when four transmit and five receive channels are needed in a compact form factor. The integrated charge pump simplifies board layout compared to discrete solutions. Verify that the 120kbps maximum data rate meets system timing constraints. Consider the shutdown current specification for battery life calculations.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX200-MAX209/MAX211/MAX213 family of +5V RS-232 transceivers. It shares architectural similarities with the MAX213 but offers different channel configurations. The family is designed for single-supply operation, reducing component count in portable designs.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX211EEWI+ serves as a pin-compatible alternative in the SOIC-28 package. Both parts share identical electrical characteristics and functionality. Verify package dimensions before substitution.
