MAX3238 - +3.0V to +5.5V / 1A / up to 250kbps / True RS-232 Transceiver with AutoShutdown Plus

General Description

The MAX3238 true RS-232 transceiver achieves a 1µA supply current with Maxim’s revolutionary 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.

Key Features

  • o 1µA Supply Current Achieved with AutoShutdown Plus o Guaranteed Data Rate: 250kbps o 1µA Low-Power Shutdown o Receivers Active in AutoShutdown Plus Mode o Flow-Through Pinout o Meets EIA/TIA-232 Specifications Down to 3.0V o Guaranteed 6V/µs Slew Rate MAX3238.

19-1144; Rev 0; 9/96 +3.0V to +5.5V, 1µA, up to 250kbps, True RS-232 Transceiver with AutoShutdown Plus™ _______________General Description The MAX3238 true RS-232 transceiver achieves a 1µA supply current with Maxim’s revolutionary 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 connected peripheral are inactive. The system turns on again when a valid transition is applied to any RS-232 receiver or transmitter input, saving power without changes to the existing BIOS or operating system.
