ADM207AN Descripción general
An RS-232 transceiver is an interface IC that translates between complementary TTL/CMOS logic and bipolar, single-ended RS-232 signals. It belongs to the communication-interface hierarchy: RS-232 interface IC → line driver and receiver → interface IC → semiconductor. Drivers amplify logic signals for a cable, while receivers detect cable voltage levels and present them to a host controller. On-board converters eliminate the need for a separate negative supply rail.
Key features include support for external charge-pump capacitors from 0.1 µF to 10 µF, a maximum data rate of 120 kB/s, and pin compatibility with the MAX206 through MAX211 and MAX213 families. Latch-up-free operation is stated in the available manufacturer-family data. The ±30 V receiver input capability provides additional tolerance to transients encountered on external cabling, although system-level protection and grounding still require engineering review.
The ADM207AN uses five driver channels and three receiver channels, allowing multiple serial functions or unused-line handling in one circuit. Its 5 V CMOS architecture simplifies interfacing with 5 V logic but requires checking input thresholds, output levels, and timing against the connected microcontroller or UART. The integrated converters generate the bipolar voltage required by RS-232 drivers without a separate negative supply.
Typical uses include industrial serial consoles, instrumentation links, data acquisition equipment, service ports, and legacy peripheral connectivity. A microcontroller UART connects to the logic-side pins, while the RS-232 pins connect through the board’s DB9 or other physical connector. Designers should verify cable length, grounding, data direction, and connector pin assignment before production.
A key design consideration is to place charge-pump capacitors close to their marked pins and provide a suitable return path for RS-232 current. Do not substitute negative logic or change connector wiring without reviewing the UART protocol. Verify propagation delay and slew-rate limits against the required baud rate, especially when long cables or slow edge rates are involved.

Aplicaciones típicas
ADM207AN es adecuado para 6 aplicacións: Industrial Serial Console, Instrumentation Data Port, Data Acquisition Controller, Legacy Peripheral Interface, Service and Configuration Port, Networking Equipment Management Port.
Industrial Serial Console
The ADM207AN fits legacy industrial console connections because its five drivers and three receivers support several RS-232 functions while a single +5 V supply eliminates the need for a separate negative rail. Verified family data specifies a 120 kB/s interface rate, approximately ±9 V driver swing, and ±30 V receiver input levels. Place the charge-pump capacitors near their marked pins, route the bipolar outputs carefully to the connector, and connect equipment grounds according to the cable plan. The interface is not an isolator, so protection, surge immunity, and enclosure grounding must be designed separately.
Recomendado
Instrumentation Data Port
ADM207AN is useful for RS-232 links in test and measurement equipment where only +5 V logic power is convenient. The integrated DC-to-DC converters generate approximately ±9 V output swing, avoiding a discrete negative supply, while three receivers can monitor more than one incoming signal. Its verified 120 kB/s rate supports many legacy instruments, but the selected instrument baud rate and protocol timing must be checked. Use short converter-capacitor connections and a controlled ground return to prevent converter or connector noise from entering the measurement system.
Recomendado
Data Acquisition Controller
The ADM207AN can connect a controller board to legacy RS-232 sensors, adapters, or laboratory modules using five driver channels and three receiver channels. A +5 V-only interface simplifies supply planning, and verified ±30 V receiver input levels add tolerance to external cable voltage excursions. These ratings do not replace surge protection or isolation. Engineers should assign logic levels, verify UART polarity, keep converter loops compact, and confirm that unused channels are deliberately configured in software or hardware before the controller is powered.
Recomendado
Legacy Peripheral Interface
ADM207AN supports upgrades of legacy peripherals that expose RS-232 through a DB9 or smaller connector and do not provide separate negative power. The verified 5 V-powered architecture produces approximately ±9 V from on-board converters, while the 120 kB/s rating covers common serial-port baud rates. Check the connector’s DB9 pin numbering because logic-side channel numbers do not by themselves define the cable wiring. Maintain one agreed ground between connected systems, use appropriate cable routing, and test with the longest intended cable before production release.
Recomendado
Service and Configuration Port
ADM207AN is appropriate for manufacturing, calibration, and field-service ports that need reliable logic-to-RS-232 conversion from a +5 V controller. Its multiple drivers can support transmit, handshake, and control lines, while three receivers permit status feedback. The verified 15 mW family value supports low-power operation, although actual consumption depends on channel activity and the exact configuration. Firmware should configure unused UART lines deliberately, and hardware should protect the external connector when cables can be longer than the bench environment.
Recomendado
Networking Equipment Management Port
The ADM207AN can implement a management or console interface on network equipment that retains an RS-232 service connector. Its five transmitters and three receivers provide enough channels for data plus flow-control signals, and operation from +5 V avoids another external negative rail. Verified receiver input capability extends to ±30 V, but cable transients still require system-appropriate protection. Keep the converter-capacitor loop compact, provide solid return-current paths, and verify isolation boundaries because the transceiver itself does not provide galvanic isolation.

Notas de diseño
Place the charge-pump capacitors specified for the ADM207AN as close as practical to their numbered pins, using short and symmetric connections. The verified family data allows 0.1 µF to 10 µF, but the selected value must come from the complete electrical table and stability or load requirements. Check capacitor polarity and voltage rating. Route each RS-232 driver output directly toward its connector or protection network rather than sharing long paths with sensitive logic; this reduces converter-current coupling and connector-current voltage drops.
Keep the logic-side UART interface and the RS-232 connector interface on separate functional regions, but provide a deliberate chassis or signal-ground return. RS-232 is single-ended and bipolar, so an arbitrary floating ground can shift receiver thresholds and impair communication. If a galvanic barrier is required, add a certified external isolator and isolated DC-to-DC supply; ADM207AN itself provides no verified galvanic-isolation rating. Check unused drivers, receivers, and converter-related pins against the final schematic before placement.
Do not treat the ADM207AN package as interchangeable with a MAX3232CD or MAX232DG4 merely because both products support RS-232. Channel counts, charge-pump pins, enable behavior, and voltage-generation arrangements can differ even when the package has 24 pins. Similarly, the verified MAX206–MAX211 family statement is not sufficient by itself to approve every MAX211 suffix. Before substitution, compare the numbered pinout, startup behavior, supply range, data rate, driver outputs, receiver inputs, shutdown controls, and PCB footprint against the fitted part.
Información de cumplimiento
The supplied verified search results do not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is treated as not applicable because ADM207AN is described as an RS-232 interface transceiver, not an automotive-qualified component in the provided data.
