ADM207AR

Overview

The ADM207AR is a CMOS RS-232 transceiver designed for EIA-232-E and V.28 communication interfaces, operating from a single +5 V power supply. It integrates five drivers and three receivers within a 24-pin package. The device utilizes internal charge pump voltage converters to generate the required ±10 V levels from the 5 V input, eliminating the need for external dual supplies. It supports data rates up to 120 kB/s with an output voltage swing of ±9 V under typical loading conditions. The component operates across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates on-board DC-to-DC charge pump converters to generate ±10 V supplies from a single 5 V source.
• Provides five TTL/CMOS-compatible drivers and three RS-232-compatible receivers in a single package.
• Features Schmitt-trigger inputs on receivers to ensure error-free reception in noisy environments.
• Includes internal pull-up resistors on driver inputs and pull-down resistors on receiver inputs.

Applications

• Computers
• Peripherals
• Modems
• Printers
• Instruments

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and compliance status. The 'AR' designation indicates a 24-lead SOIC_W package. Confirm RoHS compliance requirements by checking for the 'Z' suffix if lead-free components are mandatory for the assembly process.

Selection Notes

Select this part when five transmit channels and three receive channels are required without shutdown functionality. Unlike the ADM206 or ADM211, this model lacks low-power shutdown and enable pins. Ensure the application does not require battery-powered standby modes, as this variant consumes standard operating current continuously.

Part Context

This component belongs to the ADM2xx family of line drivers and receivers manufactured by Analog Devices. The family includes variants such as the ADM206, ADM208, ADM211, and ADM213, which offer different combinations of drivers, receivers, and control features like shutdown modes.
