DESCRIPTION

    The AT3101E is a high speed, single-channel, RS-232  transceiver interface device that operates from a single 3.3 V power supply. Low power consumption makes it ideal for battery-powered portable instruments.

     The AT3101E conforms to the RS-232 specifications and operates at data rates of up to 460 kbps.All RS-232 (TOUT and RIN) and CMOS (TIN and ROUT) inputs and outputs are protected against electrostatic discharges (up to ±15 kV ESD protection).

      Because of the ±15 kV ESD protection of the AT3101E input/output pins, this device is ideally suited for operation in electrically harsh environments or where RS-232 cables are frequently plugged and unplugged. 

     Four external 0.1 μF charge pump capacitors are used for the voltage doubler/inverter permitting operation from a single 3.3 V supply.

      The AT3101E is available in both a 12-lead LFCSP and 16-lead QSOP, specified over the −40°C to +85°C temperature range.
