The ADM3311EARU is a high-performance RS-232 transceiver designed by Analog Devices. It integrates three drivers and five receivers, enabling full-duplex serial communication at data rates up to 460 Kbps. The device operates from a single 2.7V to 3.6V power supply and features a Green Idle power-saving mode that reduces power consumption when idle. In shutdown mode, the supply current drops to typically 20 nA while one receiver remains active to monitor incoming signals.
With ESD protection exceeding 15 kV on the RS-232 I/Os per IEC 1000-4-2, the ADM3311EARU is robust for industrial and consumer applications. The receiver hysteresis of 140 mV ensures noise immunity. The device requires only 0.1 µF to 1 µF ceramic capacitors for the on-chip charge pump, which generates the RS-232 voltage levels.
The transceiver is specified over the extended industrial temperature range of -40°C to 85°C. It is housed in a 28-pin TSSOP package (0.173" width, 4.40mm body) suitable for surface mount assembly. Typical applications include mobile phones, laptops, printers, peripherals, modems, and PDAs.
