The MAX3212 us e s Ma xim’s ne w p rop rie ta ry Auto-

Shutdown mode to reduce supply current to 1µA. The

MAX3212, with 3 RS-232 drivers and 5 RS-232 receivers,

is intended for 2.7V to 3.6V-powered EIA/TIA-232E and

V.28/V.24 serial interface. True RS-232 levels are main-

tained across the operating range. A guaranteed data

rate of 235kbps provides compatibility with popular soft-

ware for communicating with personal computers.

BETTER THAN BIPOLAR!

♦ 1µA Supply Current Using AutoShutdown

♦ Operates from Single +2.7V to +3.6V Supply

♦ 28-Pin SSOP or Wide SO Packages

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

♦ Mouse Driveability–Guaranteed

♦ Low-Cost, Surface-Mount External Components

♦ 235kbps Guaranteed Data Rate–

LapLink™ Compatible

♦ +5V Logic Compatible

♦ Complementary Receiver Output Always Active

♦ Flow-Through Pinout

Supply current is reduced to 1µA with Maxim’s new

AutoShutdown feature. When the MAX3212 does not

sense a valid signal level on the receiver inputs, the on-

board power supply and drivers shut down. This occurs

if the RS-232 cable is disconnected or if the transmit-

ters of the connected peripheral are turned off. The sys-

tem turns on again when a valid level is applied to any

RS-232 receiver input. As a result, the system saves

power without changes to the existing software.

A second power-management feature is incorporated to

permit automatic shutdown when the RS-232 connection

is valid but inactive. In this case, a transition detector

facilitates shutdown when the receivers are presented

with stationary RS-232 levels for long periods.
