ADM207ARSZ - High-Speed, 5 V, 0.22 µF CMOS RS-232 Line Drivers/Receivers

The ADM207ARSZ is a robust and reliable RS-232 line driver/receiver produced by Analog Devices Inc., designed to meet the rigorous demands of high-speed data communication in industrial environments. This integrated circuit is part of a family of 5 V-powered components that facilitate bidirectional communication between data terminals and peripherals while maintaining compliance with the EIA-232E and V.28 specifications.

Constructed with Analog Devices' proprietary BiCMOS 2 process, the ADM207ARSZ offers a unique blend of high-speed operation and reduced power consumption. It is capable of operating at data rates up to 230 kbps, making it suitable for a wide range of applications that require efficient and fast serial data exchange.

The device features a quartet of line drivers and five line receivers, providing the necessary interface for a standard RS-232 port. The ADM207ARSZ is designed to withstand electrostatic discharge (ESD) events, with an impressive ESD protection level of ±15 kV on the RS-232 input/output lines, ensuring enhanced durability and reliability in harsh electrical environments.

One of the key benefits of the ADM207ARSZ is its minimal external component requirement. It only needs a single external charge pump capacitor of 0.22 µF for operation, significantly reducing the overall component count and board space. This makes it an ideal choice for space-constrained applications.

Furthermore, the ADM207ARSZ features a proprietary low-dropout transmitter output stage, delivering true RS-232 performance from a 5 V supply. This ensures compatibility with legacy systems while maintaining energy efficiency. The receivers can handle up to ±25 V input levels, and the device includes a shutdown feature that reduces the supply current to 0.1 µA, offering additional power savings when the device is not in active use.

Available in a 24-lead SSOP (Shrink Small Outline Package), the ADM207ARSZ is designed for easy integration into a variety of digital communication systems, including portable or compact devices. Its combination of high-speed operation, ESD protection, low power requirements, and reduced external components make it a versatile and essential component for any application requiring reliable RS-232 communication.
