MAX3227CAE+

The MAX3227CAE+ is a 1µA supply current, 1Mbps, 3V to 5.5V, RS232 transceiver with AutoShutdown Plus in 16 pin SSOP package. The device is 3V powered EIA/TIA-232 and V.28/V.24 communication interfaces with automatic shutdown/wakeup characteristics and high data rate capabilities. This device automatically enters to low power shutdown mode when the RS232 cable is disconnected or the transmitters of the connected peripherals are inactive. UART driving the transmitter inputs is inactive for more than 30seconds and it turn on again when they sense a valid transition at any transmitter or receiver input. AutoShutdown Plus saves power without changes to the existing BIOS or operating system. It has a logic level output (READY) that asserts when the charge pump is regulating and the device is ready to begin transmitting. This transceiver used in battery powered equipment, handheld equipment, printers, notebook, subnotebook and palmtop computers.

• Supply voltage range is 3V to 5.5V
• Operating temperature range from 0°C to 70°C
• READY output is low when charge pumps are disabled in shutdown mode & high when V- goes below -4V
• One RS232 drivers and one RS232 receivers
• Low dropout transmitter o/p stage enables RS232 performance from 3V-5.5V supply w/ dual charge pump
• Charge pump requires only four small 0.1µF capacitors for operation from a 3.3V supply
• MegaBaud operation
