ADM3101E:  ±15 kV ESD Protected, 3.3 V Single-Channel RS-232 Line Driver/Receiver

Product Description

The ADM3101E is a high speed, single-channel RS-232/V.28 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 ADM3101E conforms to the EIA/TIA-232E and CCITT V.28 specifications and operates at data rates 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).

This device is ideally suited for operation in electrically harsh environments, or where RS-232 cables are frequently being plugged/unplugged with the ±15 kV ESD protection of the I/O pins of the ADM3101E.

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 ADM3101E is available in a 12-lead LFCSP and is specified over the −40°C to +85°C temperature range.
