ADM3202/ADM3222/ADM1385 are high-speed, 2-channel RS-232/V.28 interface devices that operate from a single +3.3 V power supply. They have low power consumption and a shutdown facility, making them ideal for battery-powered portable instruments. ADM3202/ADM3222/ADM1385 conform to the EIA-232E and CCITT V.28 specifications and operate at data rates up to 460 kbps.
The ADM3202/ADM3222/ADM1385 are high-speed, 2-channel RS-232/V.28 interface devices that operate from a single +3.3 V power supply. They are designed for general-purpose RS-232 data links in portable instruments, printers, and palmtop computers. The devices utilize four external 0.1 µF charge pump capacitors to generate the required voltage levels.
