The ADM3307E/ADM3310E/ADM3311E/ADM3312E/ ADM3315E line of driver/receiver products is designed to fully meet the EIA-232 standard while operating with a single 2.7 V to 3.6 V power supply. The devices feature an on-board charge pump dc-to-dc converter， eliminating the need for dual power supplies. This dc-to-dc converter contains a voltage tripler and a voltage inverter that internally generates positive and negative supplies from the input 3 V power supply. The dc-to-dc converter operates in Green Idle™ mode， whereby the charge pump oscillator is gated on and off to maintain the output voltage at ±7.25 V under varying load conditions. This minimizes the power consumption and makes these products ideal for battery-powered portable devices. The ADM3307E/ADM3310E/ADM3311E/ADM3312E/ ADM3315E devices are suitable for operation in harsh electrical environments and contain ESD protection up to ±15 kV on their RS-232 lines （ADM3310E， ADM3311E， ADM3312E， and ADM3315E）。 The ADM3307E contains ESD protection up to ±15 kV on all I/O lines （CMOS， RS-232， EN， and SD）。 A shutdown facility that reduces the power consumption to 66 nW is also provided. While in shutdown， one receiver remains active （two receivers active with ADM3310E）， thereby allowing monitoring of peripheral devices. This feature allows the device to be shut down until a peripheral device begins communication.
