GENERAL DESCRIPTION
The ADM3101E is a high speed, single-channel, RS-232/ Because of the ±15 k V ESD protection of the ADM3101E ITU-T V.28 transceiver interface device that operates from input/output pins, this device is ideally suited for operation a single 3.3 V power supply. Low power consumption makes in electrically harsh environments or where RS-232 cables are it ideal for battery-powered portable instruments. www.BDTIC.com/ADI frequently plugged and unplugged. The ADM3101E conforms to the EIA/TIA-232E and ITU-T V.28 Four external 0.1 μF charge pump capacitors are used for the
specifications and operates at data rates of up to 460 kbps. voltage doubler/inverter permitting operation from a single
3.3 V supply.
All RS-232 (TOUT and RIN) and CMOS (TIN and ROUT) inputs
and outputs are protected against electrostatic discharges (up The ADM3101E is available in both a 12-lead LFCSP and 16-lead to ±15 k V ESD protection). QSOP, specified over the −40°C to +85°C temperature range.
