ADM3307E:  +2.7V Serial Port RS-232 Transceiver (5 Drivers / 3 Receivers) with 15kV ESD (TTL & RS-232)

Product Description

Operating from a single supply as low as +2.7 V, the ADM3307E is a five-driver/three-receiver serial port transceiver, and fully meets full EIA-232 standards. 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. It has the added benefit of having +15kV ESD protection on both the RS-232 I/O pins and the TTL pins, making it ideal for harsh environments. It also operates at speeds of up to 1Mbps. The ADM3307E is available in a 28-pin TSSOP package as well as a space-saving 32-pin LFCSP package.
