ADM213ARZ - 4/5 RS-232 Transceiver, 200 kbps | Analog Devices
MPN： ADM213ARZ ✓ 啟用中ADM213ARZ 概覽
An RS-232 transceiver is an interface IC that combines differential line drivers and receivers into a circuit capable of communicating with equipment using the EIA-232-E and V.28 physical-layer standards. The ADM213ARZ belongs to the broader hierarchy of interface ICs, communication transceivers, and semiconductors. It is intended for systems that cannot provide external ±12 V rails but still require compliant RS-232 signal levels.
The ADM213ARZ provides four transmit drivers and five receive channels, allowing one board to support multiple serial links. Its shutdown and enable controls support power management in equipment where inactive interface circuitry must not consume unnecessary power. Two receivers remain active during shutdown, enabling selected data paths to remain monitored. The 200 kbps capability is suitable for legacy serial equipment, industrial control links, service interfaces, and instrumentation.
The integrated charge-pump circuitry simplifies implementation compared with an RS-232 solution requiring external negative-voltage generation. The 4.5 V to 5.5 V operating range supports conventional 5 V system rails, while the approximately ±9 V charge-pump outputs provide the voltage swing needed to overcome RS-232 receiver thresholds. Use the manufacturer datasheet for the recommended capacitor values, driver and receiver electrical limits, enable polarity, and complete timing characteristics.
Typical applications include multi-port industrial control panels, configuration and programming ports, laboratory equipment, point-of-sale systems, and embedded systems communicating with legacy RS-232 peripherals. Multiple drivers permit several output ports, while five receivers provide additional channels for status, handshake, and incoming data signals. The shutdown function is particularly useful in portable or space-constrained systems where unused channels must be disabled.
PCB implementation should follow the manufacturer datasheet layout for the charge-pump capacitors and high-voltage RS-232 pins. Keep sensitive receiver traces away from driver outputs and switching-capacitor nodes, use the specified ceramic capacitor types, and provide adequate ground return paths. Confirm pin functions, shutdown behavior, and enable polarity against the current datasheet before assigning control signals.
This product page combines the ADM213ARZ specifications, package information, sourcing guidance, comparison points, and practical interface-design considerations. It also identifies verified same-footprint replacement candidates while clearly distinguishing them from parts that require different packages or revised circuitry.

典型應用
ADM213ARZ 適用於 6 應用s: Industrial Control Interfaces, Instrumentation and Test Systems, Embedded Configuration Ports, Point-of-Sale and Peripheral Equipment, Telecommunications and Network Support, Low-Power Portable Systems.
Industrial Control Interfaces
The ADM213ARZ fits industrial controllers, service panels, and legacy equipment requiring several RS-232 channels from one 5 V rail. Four drivers and five receivers allow command outputs, data paths, acknowledgments, and status signals to share one interface IC. Its 200 kbps maximum data rate is more than sufficient for many supervisory protocols, while shutdown support lets the controller disable unused channels. The integrated approximately ±9 V charge-pump swing removes the need for an external negative rail, although industrial deployments still require careful grounding, isolation, and surge protection.
推薦
Instrumentation and Test Systems
The ADM213ARZ is appropriate for laboratory instruments and automated test equipment that must communicate with older RS-232 peripherals. The five receivers provide dedicated inputs for measurement acknowledgments, ready signals, interlocks, and returned data, while the four drivers support outbound commands and remote stimulus control. A 200 kbps interface rate supports conventional serial control traffic, and shutdown permits measurement channels to remain connected selectively. The 28-pin SOIC package also fits densely populated instrument motherboards when the layout follows the manufacturer's pin and capacitor guidance.
推薦
Embedded Configuration Ports
The ADM213ARZ can support configuration, programming, and diagnostic ports in embedded systems that retain an RS-232 service interface. Multiple drivers and receivers reduce the number of separate interface devices needed when the product exposes bootloader, calibration, asset-tracking, or external-controller channels. Operation from a 4.5 V to 5.5 V supply aligns with conventional embedded logic rails, and the approximately ±9 V charge-pump outputs support RS-232 levels without a separate negative-voltage supply. The shutdown function is useful for reducing activity when a service connector is not in use.
推薦
Point-of-Sale and Peripheral Equipment
The ADM213ARZ fits point-of-sale terminals, scanners, printers, and peripheral controllers that need more than one RS-232 connection. Its four drivers can operate separate outbound links, and its five receivers accept acknowledgments, status lines, and incoming traffic. The 200 kbps rate accommodates common legacy peripheral protocols, while shutdown helps the host disable unused ports. The integrated charge-pump design simplifies single-5 V power architectures, while the 28-pin SOIC footprint is convenient for compact commercial control boards.
推薦
Telecommunications and Network Support
The ADM213ARZ is suitable for legacy network-access equipment, terminal servers, and communications modules that bridge modern processors to RS-232 peripherals. Four drivers and five receivers can support several console, alarm, or supervisory channels, and the 200 kbps rate is appropriate for management interfaces rather than high-speed data links. Its shutdown control helps manage idle ports in space-constrained equipment, while the approximately ±9 V internal charge-pump output provides the required RS-232 swing from a 5 V supply.
推薦
Low-Power Portable Systems
The ADM213ARZ can serve portable and battery-operated equipment that retains an RS-232 diagnostic or configuration interface. Its low-power shutdown mode allows most drivers and receivers to be disabled, while two receivers remain active for selected monitoring or handshake signals. The 200 kbps maximum data rate allows the port to be used for setup, diagnostics, or short data transfers without a high-speed physical layer. Operation from a 4.5 V to 5.5 V supply supports portable systems using a regulated 5 V rail.

主要差異化特點
- Five receivers support richer multi-channel RS-232 connectivity (對比MAX213CWI)
- Shutdown preserves two monitoring channels (對比MAX213CWI)
- 200 kbps interface rate exceeds typical supervisory-link requirements (對比ADM213EARSZ)
- Single-rail interface generation uses approximately ±9 V charge-pump outputs (對比MAX213CWI)
設計說明
Place the 0.1 µF charge-pump capacitors close to their designated pins and follow the Analog Devices ADM213 datasheet layout exactly. The switching network associated with the approximately ±9 V charge-pump outputs can couple noise into adjacent circuitry. Keep sensitive receiver routes away from capacitor connections and driver outputs, and preserve the recommended ground-return geometry to minimize common-impedance disturbance.
Route each RS-232 driver output as a distinct signal and avoid sharing narrow traces or introducing long stubs. The four-driver capability does not imply that outputs should be paralleled. Confirm receiver input thresholds, driver slew behavior, and maximum cable loading in the manufacturer datasheet. Use an appropriate line-protection strategy when exposed cables or industrial transients are part of the system.
Decouple the 5 V supply locally and provide a low-impedance return for the transceiver and charge-pump network. The documented operating range is 4.5 V to 5.5 V, so do not allow supply tolerance, transient overshoot, or regulator ripple to move outside that range. Evaluate bulk and local ceramic capacitance according to the manufacturer's application guidance and the switching characteristics of the selected supply.
Do not infer pin compatibility from the 28-pin SOIC package alone. The ADM213ARZ has four drivers, five receivers, shutdown behavior with two active receivers, and defined enable and shutdown controls. Before substituting MAX213CWI, compare every pin name and control polarity. Also confirm that the target board uses the same 0.1 µF capacitor arrangement rather than a charge-pump topology with different values.
