MAX213CWI+T

Drivers, Receivers, Transceivers Overview

The MAX213CWI+T is a +5V RS-232 transceiver featuring integrated charge pump circuitry for single-supply operation. It provides four drivers and five receivers in a 28-pin wide SO package. The device supports data rates exceeding 120kbps with ±5V output levels under EIA/TIA-232E loads. Operating voltage ranges from 4.5V to 5.5V, with an operating temperature range of 0°C to +70°C. Supply current is typically 20mA in active mode and 50µA in shutdown.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump eliminates the need for external bipolar supplies
• Shutdown mode reduces power consumption for battery applications
• Two receivers remain active during shutdown for ring indicator monitoring

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the component designation against official manufacturer documentation to confirm pinout compatibility and electrical specifications. Ensure the ordering suffix matches the required temperature grade and packaging format. Cross-reference datasheet revision numbers to validate functional parameters before integration into production designs.

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 capacitors usually required for voltage inversion. Verify that the thermal dissipation capabilities of the 28-pin wide SO package meet the application's power requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX200-MAX209/MAX211/MAX213 family of RS-232 transceivers. These devices share common architecture but differ in driver/receiver counts and control features. The MAX213 specifically includes five receivers and dedicated ring indicator monitoring capabilities not found in other family members.

Drivers, Receivers, Transceivers FAQ

How does the MAX213 handle unused driver inputs?

Unused driver inputs have internal 400kΩ pullup resistors to VCC, forcing outputs low to minimize power consumption.

What is the function of the EN pin on the MAX213?

The EN pin places receiver outputs into a high-impedance state, allowing direct connection to three-state buses without affecting drivers or charge pumps.

Can the MAX213 operate with a single +5V supply?

Yes, the integrated charge pump generates the necessary ±10V rails internally from a single +5V input.
