BETTER THAN BIPOLAR!

The MAX3218 RS-232 transceiver is intended for bat-

tery-powered EIA/TIA-232E and V.28/V.24 communica-

tions interfaces that need two drivers and two receivers

with minimum power consumption from a single low-

voltage supply. It provides a wide +1.8V to +4.25V

operating voltage range while maintaining true RS-232

and EIA/TIA-562 voltage levels. The MAX3218 runs

from two alkaline, NiCd, or NiMH cells without any form

of voltage regulator. A guaranteed 120kbps data rate

provides compatibility with popular software for com-

municating with personal computers.

♦ 1µA Supply Current Using AutoShutdown™

♦ Operates Directly from Two Alkaline,

NiCd or NiMH Cells

♦ +1.8V to +4.25V Single-Supply Voltage Range

♦ 120kbps Data Rate Guaranteed

♦ Low-Cost Surface-Mount Components

♦ Meets EIA/TIA-232E Specifications

♦ Three-State Receiver Outputs

♦ Flow-Through Pinout

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

AutoShutdown™ feature. When the MAX3218 does not

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

b oa rd p owe r-s up p ly a nd d rive rs s hut d own. This

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

transmitters of the connected peripheral are turned off.

The system turns on again when a valid level is applied

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

saves power without changes to the existing software.

Additionally, the MAX3218 can be forced into or out of

shutdown, under logic control.

♦ On-Board DC-DC Converters

♦ 20-Pin SSOP and DIP Packages

While shut down, all receivers can remain active or can

be disabled under logic control, permitting a system

incorporating the CMOS MAX3218 to monitor external

devices while in low-power shutdown. Three-state dri-

vers are provided on both receiver outputs so that multi-

ple receivers, generally of different interface standards,

can be on the same bus. The MAX3218 is available in

20-pin DIP and SSOP packages.
