MAX213ECAI+T

Drivers, Receivers, Transceivers Overview

The MAX213ECAI+T is a single-supply RS-232 transceiver from the MAX202E–MAX213E family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a +4.5V to +5.5V supply and integrates charge-pump circuitry to generate ±10V levels without external bipolar supplies. The device features four drivers and five receivers, with two receivers (R4, R5) remaining active during shutdown for wake-up functionality. It supports data rates up to 120kbps and provides ±15kV ESD protection via Human Body Model testing. The component is housed in a 28-pin SSOP package and functions within an industrial temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated high ±15kV HBM ESD protection on driver outputs and receiver inputs
• Single +5V supply operation enabled by internal charge-pump voltage converters
• Two awake-in-shutdown receivers allow monitoring of external activity while maintaining low power consumption
• CMOS/TTL-compatible input thresholds ensure reliable signal detection

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring low standby current
• Hand-held diagnostic tools
• Portable communication devices

Drivers, Receivers, Transceivers Procurement Notes

Verify the ordering suffix 'CAI' corresponds to the specific 28-pin SSOP package variant and the '-E' designation indicating the extended temperature range (-40°C to +85°C). Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure pinout compatibility with existing PCB layouts designed for the standard MAX213E family.

Drivers, Receivers, Transceivers Selection Notes

Select this component when design requirements include single-supply operation combined with specific wake-up capabilities on two receiver channels. The integrated charge pump eliminates the need for external bipolar voltage sources, reducing board space. Consider the 28-pin SSOP footprint constraints and verify that the 120kbps maximum data rate meets system timing specifications.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX202E–MAX213E family of RS-232 transceivers. Unlike the MAX211E, which has all receivers inactive in shutdown, the MAX213E uniquely retains functionality on receivers R4 and R5 during shutdown mode. This distinction allows for selective port monitoring in multi-port systems without increasing overall power consumption significantly.

Drivers, Receivers, Transceivers FAQ

How does the MAX213E differ from the MAX211E regarding shutdown mode?

In shutdown mode, the MAX213E keeps receivers R4 and R5 active to monitor external signals, whereas all receivers on the MAX211E are placed in a high-impedance state.

What is the polarity of the Enable and Shutdown control pins for the MAX213E?

For the MAX213E, the Enable (EN) pin is active high, and the Shutdown (SHDN) pin is active low. This is reversed compared to the MAX211E and MAX241E.

What capacitor values are required for the charge pump?

The MAX213E requires four 0.1μF capacitors for the charge pump circuitry (C1–C4).
