Product Details

Operating from a single supply as low as +2.7 V, the ADM3315E is a three-driver/three-receiver serial port transceiver, and fully meets full EIA-232 standards.  It is similar to the ADM3312E but with the Power Supply Current reduced by up to 50%.  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 ADM3315E is available in a 24-pin TSSOP package as well as a space-saving 5*5mm 32-pin LFCSP package.
