+5V-Powered, Multichannel

RS-232 Drivers/Receivers

MAX220–MAX249

General Description

Benefits and Features

Saves Board Space

The MAX220–MAX249 family of line drivers/receivers is

intended for all EIA/TIA-232E and V.28/V.24 communica-

tions interfaces, particularly applications where 12V is

not available.

• Integrated Charge Pump Circuitry

• Eliminates the Need for a Bipolar 12V Supply

• Enables Single Supply Operation from +5V Supply

The MAX225, MAX233, MAX235, and MAX245/MAX246/

MAX247 use no external components and are

recommended for applications where printed circuit

board space is critical.

• Integrated Capacitors (MAX223, MAX233, MAX235,

MAX245-MAX247)

Saves Power for Reduced Power Requirements

• 5µW Shutdown Mode

The MAX220-MAX249 are offered in 26 different pack-

ages with temperatures from 0 to +70°C up to -55°C to

+125°C. See ordering information table at the end of the

data sheet for all package and temperature options.

Ordering Information and Selection Table appears at end

of data sheet.

Applications

• Interface Translation

• Multidrop RS-232 Networks

• Portable Diagnostics Equipment
