2.7 V Serial Port RS-232 Transceiver (3 Drivers / 5 Receivers) with 15V ESD

The ADM3310E is a three-driver/five-receiver serial port transceiver, which meets EIA-232 standards while operating from a single power supply as low as +2.7V. It is similar to the ADM3311E but with two of the Receivers remain Active during Shutdown. 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 +/-6 V, regardless of the load conditions. Another key feature is its ESD protection: up to +/−15kV on all I/O lines. The ADM3310E is available in a 28-pin TSSOP package as well as a space-saving 5×5mm 32-pin LFCSP package.
