________________General Desc ription
The MAX3224–MAX3227/MAX3244/MAX3245 are 3V-
powered EIA/TIA-232 and V.28/V.24 communications
interfaces with automatic shutdown/wakeup features
and high data-rate capabilities.
All devices achieve a 1μA supply current using Maxim’s
revolutionary AutoShutdown Plus feature. These
devices automatically enter a low-power shutdown
mode when the RS-232 cable is disconnected or the
transmitters of the connected peripherals are inactive,
and the UART driving the transmitter inputs is inactive
for more than 30 seconds. They turn on again when
they sense a valid transition at any transmitter or receiv-
er input. AutoShutdown Plus saves power without
changes to the existing BIOS or operating system.
The MAX3225/MAX3227/MAX3245 also feature
MegaBaud operation, guaranteeing 1Mbps for high-
speed applications such as communicating with ISDN
modems. The MAX3224/MAX3226/MAX3244 guarantee
250kbps operation. The transceivers have a proprietary
low-dropout transmitter output stage enabling true RS-
232 performance from a +3.0V to +5.5V supply with a
dual charge pump. The charge pump requires only four
small 0.1μF capacitors for operation from a 3.3V supply.
The MAX3224–MAX3227 feature a logic-level output
(READY) that asserts when the charge pump is regulat-
ing and the device is ready to begin transmitting.
All devices are available in a space-saving SSOP pack-
age.
