ADM3232EARNZ: High-Speed, Dual-Channel RS-232 Transceiver with 15kV ESD Protection
The ADM3232EARNZ is a high-performance RS-232/V.28 interface transceiver designed by Analog Devices (ADI) for robust serial communication in industrial and portable applications. Operating from a single 3.0V to 5.5V power supply, it supports data rates up to 460 kbps while consuming minimal power (3mA max supply current), making it ideal for battery-powered devices. The device features two drivers and two receivers, enabling full-duplex communication, and integrates a charge pump circuit requiring only four 0.1μF external capacitors for voltage conversion. Its ±15 kV ESD protection (contact/air gap) on all RS-232 I/O pins ensures reliability in harsh environments, complying with IEC 1000-4-2 standards. The ADM3232EARNZ is available in a compact 16-pin SOIC package, supporting operating temperatures from -40°C to +85°C, and is RoHS-compliant.
Key Features and Applications
The ADM3232EARNZ excels in applications requiring reliable, high-speed RS-232 communication. Its low-power CMOS design minimizes energy consumption, extending battery life in portable instruments like handheld terminals and medical devices. The transceiver meets EIA-232E and ITU-T V.28 specifications, ensuring compatibility with legacy and modern RS-232 systems. Key features include 5kΩ internal pull-down resistors on RS-232 inputs for stable idle states, strict emission control to meet regulatory limits, and thermal shutdown protection to prevent overheating. Typical applications include industrial diagnostic ports, telecommunications equipment, and general-purpose data links where ESD resilience and compact size are critical.
Alternative Transceiver Models and Key Differences
● MAX3232EUE+: A Maxim Integrated alternative with similar 460 kbps data rate and 15kV ESD protection, but in a smaller 16-pin TSSOP package.
● SP3232EEN-L/TR: A cost-effective option from Exar (now Renesas) with 250 kbps data rate and 15kV ESD protection, suitable for budget-sensitive applications.
● ICL3232IBNZ: An Intersil variant offering 230 kbps data rate and 15kV ESD protection, featuring a wider 4.5V–5.5V supply range for industrial systems.
