Overview
The ADM3315EARUZ-REEL, produced by Analog Devices Inc., is a low-power, triple transmitter and triple receiver RS-232 transceiver. This device is part of the ADM33xxE series, designed to meet the EIA-232 standard while operating with a single supply voltage of 2.7 V to 3.6 V. It is ideal for battery-powered portable devices and operates in harsh electrical environments, providing ESD protection up to ±15 kV on its RS-232 lines. The ADM3315E is particularly suited for applications in PDAs, palmtop computers, and mobile phone data cables due to its low current consumption and high receiver input resistance, which reduces the drive requirements of the Data Terminal Equipment (DTE).
