The MAX3238 true RS-232 tra ns c e ive r a c hie ve s a

1µA s up p ly c urre nt with Ma xim’s re volutiona ry

AutoShutdown Plus feature. When the device does not

sense a valid signal transition on either the receiver or

transmitter inputs within 30sec, the on-board power

supply and drivers shut down. This occurs if the RS-232

cable is disconnected or if the transmitters of the con-

nected peripheral are inactive. The system turns on

again when a valid transition is applied to any RS-232

re c e ive r or tra ns mitte r inp ut, s a ving p owe r without

changes to the existing BIOS or operating system.

♦ 1µA Supply Current Achieved with

AutoShutdown Plus

♦ Guaranteed Data Rate: 250kbps

♦ 1µA Low-Power Shutdown

♦ Receivers Active in AutoShutdown Plus Mode

♦ Flow-Through Pinout

♦ Meets EIA/TIA-232 Specifications Down to 3.0V

♦ Guaranteed 6V/µs Slew Rate

The MAX3238 5-driver/3-receiver complete serial port is

a 3V-powered EIA/TIA-232 and V.28/V.24 communica-

tions interface intended for notebook or subnotebook

computer applications. 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 250kbps provides compatibility with popu-

lar software for communicating with personal comput-

ers. The MAX3238 requires only 0.1µF capacitors in

3.3V operation. It is ideal for 3.3V-only systems, mixed

3.3V and 5.0V systems, or 5V-only systems that require

true RS-232 performance.
