Overview
The ADM207EARZ is an RS-232 line transceiver from the ADM2xxE family, manufactured by Analog Devices. It operates on a single 5 V power supply and features five drivers and three receivers for full-duplex communication. The device supports data rates up to 230 kbps and includes internal charge pumps requiring only four external 0.1 μF capacitors. It provides ±15 kV ESD protection on all I/O lines and complies with EMC directives. The component is housed in a 24-lead SOIC package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Complies with EU EMC directive (89/336/EEC) with low emissions and high immunity.
- Provides robust ESD protection exceeding ±15 kV on all input/output lines.
- Operates from a single 5 V supply using an internal charge pump.
- Supports high-speed data transmission up to 230 kbps.
Applications
- Laptop computers
- Notebook computers
- Printers
- Peripherals
- Modems
Procurement Notes
Verify the specific package suffix against the ordering guide to ensure correct physical dimensions and pinout compatibility. Confirm that the required operating voltage and environmental temperature ranges align with the system design specifications before finalizing procurement decisions.
Selection Notes
Select this component when a five-driver, three-receiver configuration is required without shutdown control features. Ensure the design accommodates the 24-lead SOIC footprint and utilizes four external 0.1 μF capacitors for the charge pump circuitry to maintain optimal performance.
Part Context
The ADM207EARZ belongs to the ADM2xxE series of ruggedized RS-232 interface devices. This family is designed for harsh electrical environments and offers backward compatibility with earlier ADM2xx products. The 'E' designation indicates enhanced EMI/EMC compliance and superior ESD protection compared to standard variants.
Replacement Considerations
Public confirmed substitute part numbers: ADM207EARUZ.
FAQ
Does the ADM207EARZ include a shutdown mode?
No, the ADM207E variant does not feature shutdown or enable control pins. These functions are available on other members of the family, such as the ADM211E and ADM213E.
What external components are required for operation?
The device requires four external 0.1 μF capacitors connected to the charge pump pins (C1+, C1-, C2+, C2-) to generate the necessary positive and negative voltages from the single 5 V supply.
How is ESD protection implemented on this device?
All I/O lines incorporate protective clamping structures that provide ESD protection up to ±15 kV according to the Human Body Model and ±15 kV air-gap discharge per IEC 1000-4-2 standards.
