ADM3312EARUZ: +2.7V Serial Port RS-232 Transceiver (3 Drivers / 3 Receivers) with 15kV ESD
The ADM3312E is a three-driver/three-receiver serial port transceiver, which meets full EIA-232 standards while operating from a single power supply as low as +2.7V. It features an on-board, charge pump dc-to-dc converter, which eliminates the need for dual power supplies. This dc-to-dc converter also contains a voltage tripler and voltage inverter for internally generating positive and negative supplies from the power supply. It operates in Green Idle Mode, where the charge pump oscillator is gated on and off to maintain output voltage to +/-7.25 V, regardless of the load conditions. Another key feature is its ESD protection: up to +/-15kV on all I/O lines. The ADM3312E is available in a 24-pin TSSOP package as well as a space-saving 32-pin LFCSP package.
