ADM3307EARU-REEL by Analog Devices Inc.

The ADM3307EARU-REEL is a high-performance, low-power, 3.3V RS-232 line driver/receiver interface device from the renowned manufacturer Analog Devices Inc. This component is designed to meet the stringent EIA/TIA-232E and V.28/V.24 specifications, even at data rates up to 250 kbps. Its innovative design ensures that it operates with a single 3.3V power supply, making it an ideal choice for portable and space-constrained applications where power efficiency is crucial.

Featuring an integrated charge pump circuit, the ADM3307EARU-REEL can generate the necessary ±5.5V RS-232 voltage levels using only four small 0.1 µF external capacitors. This charge pump and the device's low-power shutdown mode contribute to its minimal power consumption, making it an eco-friendly choice for power-sensitive designs.

The device comes in a space-saving 44-lead TSSOP (Thin Shrink Small Outline Package) and is part of the REEL packaging variant, which indicates that it is provided in tape and reel form for automated assembly processes. This packaging is particularly useful for high-volume production environments, ensuring efficiency and ease of integration into PCB assemblies.

The ADM3307EARU-REEL is equipped with a variety of features that enhance its performance and reliability. It includes two drivers and two receivers, which makes it suitable for full-duplex communication. Additionally, it boasts a 1 µA low-power shutdown mode, receiver hysteresis for improved noise immunity, and a guaranteed data rate of 250 kbps. The device also features a logic-selectable two-driver operation that allows users to disable the charge pump and drivers for even lower power consumption when not in use.

Engineered for robustness, the ADM3307EARU-REEL incorporates protection against electrostatic discharge (ESD) up to ±15 kV on the RS-232 input/output lines, safeguarding the device against the harsh realities of real-world environments. Whether implemented in battery-powered devices, PDAs, notebooks, or any other RS-232 communication interfaces, this product from Analog Devices Inc. offers an optimal blend of performance, power efficiency, and space-saving design.
