ADM3222ARSZ RS-232接口IC

ADM3222ARSZ

RS-232接口集成电路 High-Speed 2-Channel 3.3V

Low Power, 3.3 V, RS-232  Line Drivers/Receivers

GENERAL DESCRIPTION ADM3222ARSZ

The ADM3202/ADM3222/ADM1385 transceivers are high

speed, 2-channel RS-232/V.28 interface devices that operate

from a single 3.3 V power supply. Low power consumption and

a shutdown facility (ADM3222/ADM1385) make them ideal for

battery-powered portable instruments.

The ADM3202/ADM3222/ADM1385 parts conform to the

EIA-232E and CCITT V.28 specifications and operate at data

rates up to 460 kbps.

Four external 0.1 μF charge pump capacitors are used for the

voltage doubler/inverter, permitting operation from a single

3.3 V supply.
