1µA Supply Current, 1.8V to 4.25V-Powered

RS-232 Transceiver with AutoShutdown™

_______________General Description

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.

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

AutoShutdown™ feature. When the MAX3218 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

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.

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.
