ADM208EANZ - High-Speed, 5 V, 0.1 uF CMOS RS-232 Drivers/Receivers

The ADM208EANZ is a robust RS-232 transceiver solution from Analog Devices Inc., designed to facilitate reliable serial communication in a variety of applications. This integrated circuit is part of a family of high-speed transceivers that operate from a single 5 V power supply and are capable of running at data rates up to 230 kbps. The ADM208EANZ is particularly suited for environments where ±15 kV ESD protection is essential.

This device features a quartet of drivers and receivers, making it ideal for full-duplex communication. Each driver and receiver has been designed to handle ±30 V input levels, and the high impedance receiver inputs are maintained even when the device is powered off, which reduces power consumption and extends battery life in portable applications.

The ADM208EANZ offers a slew rate limited version for applications that require reduced EMI and reflections, ensuring clean signal transmission and reception over longer cable runs. This makes it an excellent choice for industrial control systems, point of sale equipment, and other applications that require robust and reliable data transmission.

Key features of the ADM208EANZ include:

• Meets EIA-232E Specifications
• 230 kbps Transmission Rate
• 0.1 uF Charge Pump Capacitors
• ±15 kV ESD Protection on RS-232 Input/Output Pins
• Two Receivers Remain Active in Shutdown Mode
• Wide Operating Temperature Range: -40°C to +85°C
• 28-Pin Narrow SOIC Package

The device's shutdown mode reduces power consumption by shutting down the charge pump and disabling the drivers when not in use, while still allowing the receivers to monitor for incoming signals. This feature is particularly useful in battery-powered applications where conserving power is critical.

In summary, the ADM208EANZ from Analog Devices Inc. is a reliable and efficient solution for RS-232 communication, providing high-speed data transfer, robust ESD protection, and low power consumption in a compact form factor. It is an excellent choice for designers looking to implement RS-232 interfaces in their systems.
