SUPERIOR TO BIPOLAR:

♦ Operates from Single +3.0V to +3.6V Supply

The MAX212 RS-232 transceiver is intended for 3V-pow-

ered EIA/TIA-232E and V.28/V.24 communication inter-

faces where 3 drivers and 5 receivers are needed with

minimum power consumption. The operating voltage

range extends from 3.6V down to 3.0V while still main-

taining true RS-232 and EIA/TIA-562 voltage levels.

♦ 24-Pin SSOP or Wide SO Packages

♦ Meets All EIA/TIA-232E & EIA/TIA-562

Specifications

A 1µA typical shutdown mode reduces power con-

sumption, extending battery life in portable systems.

While shut down, all receivers can remain active or can

be disabled under logic control. This enables a system

incorporating the CMOS MAX212 to be in low-power

shutdown mode and monitor incoming RS-232 activity.

A guaranteed data rate of 120kbps provides compati-

bility with popular software for communicating with per-

sonal computers.

♦ 3mA Max Supply Current (Unloaded)

♦ 1µA Low-Power Shutdown Mode

♦ All Receivers Active During Low-Power Shutdown

♦ Mouse Compatible at 3.0V

♦ Low-Cost, Surface-Mount External Components

♦ 120kbps Guaranteed Data Rate—LapLink™

Compatible

Three-state drivers on all receiver outputs are provided

so that multiple receivers, generally of different inter-

face standards, can be wire-ORed at the UART.

The MAX212 is available in both small-outline (SO) and

s hrink-s ma ll-outline (SSOP) p a c ka g e s . The SSOP

package occupies less than half of the board area

required by the equivalent SO package.

♦ Three-State Receiver Outputs

♦ Evaluation Kit Available

♦ Flow-Through Pinout
