Analog Devices ADM248BRWZ Interface IC - RS-232 Transceiver

The ADM248BRWZ is a high-performance interface IC from Analog Devices Inc., designed to meet the stringent requirements of EIA/TIA-232 and V.28/V.24 specifications, even at data rates up to 460 kbps. This RS-232 transceiver is a perfect solution for applications requiring reliable serial communication, including industrial control systems, point-of-sale terminals, and modem interface designs.

Encapsulated in a 16-lead SOIC wide package, the ADM248BRWZ is engineered to operate with a single +5V power supply, making it an ideal choice for systems that have limited power availability. Its low-power shutdown mode further conserves energy, allowing for efficient operation in battery-powered devices.

One of the distinguishing features of the ADM248BRWZ is its enhanced electrostatic discharge (ESD) protection. It is capable of withstanding ±15kV discharges on the RS-232 input/output lines, which is essential for preventing damage during installation and everyday use in harsh environments. This robust protection is in line with the IEC 1000-4-2 specification, providing peace of mind for the longevity of your application.

The device boasts a charge pump circuit that requires only four small 0.1 µF external capacitors for operation. This charge pump and the capacitors form a voltage doubler/inverter, which enables the transceiver to deliver RS-232 voltage levels from a single 5V supply. This innovative design simplifies the overall circuit layout and reduces the required PCB space, making the ADM248BRWZ a compact and effective solution for space-constrained applications.

With its wide temperature range of -40°C to +85°C, the ADM248BRWZ is suited for use in a variety of environments, ensuring reliable operation even under extreme conditions. Its integrated power-on reset circuit ensures that the RS-232 driver outputs remain in a high impedance state until the power supply has stabilized, further enhancing the reliability of the communication interface.

For designers looking for a dependable, high-speed RS-232 transceiver with advanced features and protection, the ADM248BRWZ from Analog Devices Inc. is an exceptional choice that promises to deliver performance, efficiency, and durability.
