ADM207ARZ-REEL

Overview

The ADM207ARZ-REEL is a CMOS RS-232 transceiver manufactured by Analog Devices Inc., designed for EIA-232-E and V.28 communication interfaces. It integrates five drivers and three receivers, operating from a single +5 V supply with an internal charge pump generating ±10 V rails. The device supports data rates up to 120 kB/s and requires four external capacitors ranging from 0.1 μF to 10 μF. It lacks shutdown or enable control inputs. Electrical specifications include a typical output voltage swing of ±9 V, a maximum power supply current of 13 mA, and an input logic threshold high of 2.0 V. The component operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates on-board DC-to-DC converters to generate required RS-232 voltages from a single 5 V supply
• Features Schmitt-trigger receiver inputs with hysteresis for noise immunity
• Includes internal pull-up resistors on transmitter inputs and pull-down resistors on receiver inputs
• Provides latch-up free protection for reliable operation

Applications

• Computers
• Peripherals
• Modems

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and RoHS compliance status. Confirm that the REEL designation matches the required tape and reel packaging format for automated assembly processes. Ensure the part number corresponds to the correct temperature grade and pin configuration before procurement.

Selection Notes

Select this component when five independent RS-232 drivers are required alongside three receivers. It is suitable for applications where low power shutdown functionality is not necessary. Verify that the system design can accommodate the required four external capacitors for the charge pump circuitry. Ensure the interface logic levels are compatible with the specified TTL/CMOS thresholds.

Part Context

This component belongs to the ADM2xx family of line drivers and receivers developed by Analog Devices. The family includes variants such as the ADM206, ADM208, ADM211, and ADM213, which offer different combinations of drivers and receivers or additional control features like shutdown modes. The ADM207 specifically provides a fixed configuration of five drivers and three receivers without enable controls.
