The MAX3221/MAX3223/MAX3243 achieve 1µA supply

current with Maxim’s revolutionary AutoShutdown™ fea-

ture. When the MAX3221/MAX3223/MAX3243 do not

sense a valid signal level on their 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 any RS-232 receiver input. As a result, the system

saves power without changes to the existing BIOS or

operating system.

The MAX3221/MAX3223/MAX3243 transceivers are 3V-

powered EIA/TIA-232 and V.28/V.24 communications

interfaces intended for notebook computer applica-

tions. A proprietary, high-efficiency, dual charge-pump

power supply and a low-dropout transmitter combine to

deliver true RS-232 performance from a single +3.0V to

+5.5V supply. A guaranteed data rate of 120kbps pro-

vides compatibility with popular software for communi-

cating with personal computers.

The MAX3221/MAX3223/MAX3243 require only 0.1µF

capacitors in 3.3V operation, and can operate from input

voltages ranging from +3.0V to +5.5V. They are ideal for

3.3V-only systems, mixed 3.3V and 5.0V systems, or

5.0V-only systems that require true RS-232 performance.

The MAX3221 is a 1-driver/1-receiver 16-pin SSOP ver-

sion of the 20-pin MAX3223 (2-driver/2-receiver). The

MAX3243 3-driver/5-receiver, complete serial port is

ideal for notebook or subnotebook computers. The

MAX3243 includes one complementary always-active

receiver. This receiver can monitor an external device

(such as a modem) in shutdown, without forward bias-

ing the protection diodes in a UART that may have V

completely removed.
