15千伏ESD保護(hù)3.3伏RS線路驅(qū)動(dòng)器/接收機(jī)adm3232e

　　The ADM3232E transceiver is a high speed， 2-channel RS-232/V.28 interface device that operates from a single 3.3 V power supply. Low power consumption makes it ideal for battery-powered portable instruments. The ADM3232E conforms to the EIA-232E and ITU-T V.28 specifications and operates at data rates up to 460 kbps. All RS-232 （TxOUT and RxIN） inputs and outputs are protected against electrostatic discharges （up to ±15 kV ESD protection）。 This ensures compliance with IEC 1000-4-2 requirements. This device is ideally suited for operation in electrically harsh environments or where RS-232 cables are frequently plugged/ unplugged， with the ±15 kV ESD protection of the ADM3232E RS-232 input/output pins. Emissions are also controlled to within very strict limits. CMOS technology is used to keep the power dissipation to an absolute minimum， allowing maximum battery life in portable applications. 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 ADM3232E is available in a 16-lead narrow and wide SOIC packages， as well as a space-saving 16-lead TSSOP.
