MAX3248E Datasheet | Maxim Integrated

Description The MAX3238E/MAX3248E transceivers use Maxim’s revolutionary Auto Shutdown Plus™ feature to achieve 10n A supply current. These devices shut down the onboard power supply and drivers when they do not sense a valid signal transition on either the receiver or transmitter inputs. This occurs if the RS-232 cable is disconnected or if the transmitters of the connected peripheral are turned off. The devices turn on again when a valid transition is applied to any RS-232 receiver or transmitter input. Auto Shutdown Plus automatically achieves this power savings through its on-board circuitry, as no changes are required to the existing BIOS or operating system. All RS-232 inputs and outputs, as well as the logic I/O pins, have enhanced ESD protection to ±15k V. The additional ESD protection on the logic I/O pins makes the...
