Overview
The ADM3232EARUZ-REEL7, produced by Analog Devices Inc., is a high-speed, 2-channel RS-232/V.28 interface device. It operates from a single 3.3V power supply, making it ideal for battery-powered portable instruments due to its low power consumption. This device is particularly suited for operation in electrically harsh environments or where RS-232 cables are frequently plugged/unplugged, thanks to its ±15 kV ESD protection on all RS-232 inputs and outputs. The ADM3232E conforms to the EIA-232E and ITU-T V.28 specifications and supports data rates up to 460 kbps.
