MAX200–MAX209/

MAX211/MAX213

+5V, RS-232 Transceivers

with 0.1μF External Capacitors

General Description

MAX200-MAX209, MAX211, and MAX213 are a family

of RS-232 and V.28 transceivers with integrated charge

pump circuitry for single +5V supply operation.

The drivers maintain the ±5V EIA/TIA-232E output signal

levels at data rates in excess of 120kbps when loaded in

accordance with the EIA/TIA-232E specification.

The MAX211 and MAX213 are available in a 28-pin, wide

small-outline (SO) package and a 28-pin shrink small-

outline (SSOP) package, which occupies only 40% of the

area of the SO. The MAX207 is available in a 24-pin SO

package and a 24-pin SSOP. The MAX203 and MAX205

use no external components and are recommended for

applications with limited circuit board space.

Benefits and Features

●● Saves Board Space

• Integrated Charge Pump Circuitry

Eliminates the Need for a Bipolar ±12V Supply

Enables Single Supply Operation From Either +5V

or 9V to +12V

• Integrated 0.1μF Capacitors (MAX203, MAX205)

• 24 pin SSOP Package Saves Up to 40% Versus

SO Package

●● Saves Power for Longer Battery Operation

• 5μW Shutdown Mode (MAX200, MAX205,

MAX206, MAX211)

• 75μW Ring Indicator Monitoring with Two Active

Receivers (MAX213)

Applications

●● Battery-Powered Equipment

●● Handheld Equipment

●● Portable Diagnostics Equipment
