Replacement verdict
Compatible functional replacement candidate
The ADM213EARSZ and ADM211ARS-REEL are both RS-232 transceivers from Analog Devices in a 28-pin SSOP package, sharing the same interface standard, supply voltage range, and pinout family, making them strong functional replacement candidates. The ADM213EARSZ offers four drivers and five receivers with a higher data rate and enhanced ESD protection, while the ADM211ARS-REEL provides four drivers and four receivers. Designers should validate the receiver channel count and data rate requirements against the target application before substituting one for the other.

Key electrical and mechanical differences between the two devices
| Parameter | ADM213EARSZ | ADM211ARS-REEL | Why it matters |
|---|---|---|---|
| Number of Drivers | 4 | 4 | Driver count determines how many transmit lines the interface can drive; both match here. |
| Number of Receivers | 5 | 5 | Receiver count determines how many receive lines are supported; both match here. |
| Data Rate | 120 kbps | 120 kbps | Maximum data rate must meet the application's signaling speed; both are rated at 120 kbps. |
| Supply Voltage | 5 V | 5 V | The operating supply voltage must match the system rail; both operate from a single 5 V supply. |
| ESD Protection (IEC 1000-4-2) | ±15 kV (air), ±8 kV (contact) | ±15 kV (air), ±8 kV (contact) | ESD rating affects robustness in harsh environments; both offer the same enhanced ESD protection. |
| Package / Mounting | 20-SSOP (surface mount) | 20-SSOP (surface mount) | Package and footprint must match the PCB layout for drop-in substitution; both use a 20-lead SSOP. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Temperature range must cover the application environment; both are rated for industrial temperature ranges. |
| Charge Pump / Capacitor Configuration | Internal charge pump, 4 external capacitors | Internal charge pump, 4 external capacitors | External capacitor count affects board space and BOM; both require the same external capacitor arrangement. |
| Shutdown / Enable Feature | Yes (active-low shutdown) | Yes (active-low shutdown) | Shutdown capability affects power management and pin compatibility; both provide an active-low shutdown pin. |

Frequently asked questions
What are the key differences between the ADM213EARSZ and ADM211ARS-REEL?
The ADM213EARSZ is a 5 V, dual-channel RS-232 line driver/receiver with a shutdown mode and a minimum data rate of 120 kbps, supplied in a 28-lead SSOP package. The ADM211ARS-REEL is a 5 V, dual-channel RS-232 line driver/receiver without shutdown, specified at 120 kbps, supplied in a 28-lead SSOP package on tape and reel. The primary differences are the shutdown feature (present on the ADM213E, absent on the ADM211) and the packaging format (tube/tray versus tape and reel).
Are the ADM213EARSZ and ADM211ARS-REEL pin-compatible?
Both devices are offered in the same 28-lead SSOP (RS-28) package, but they are not functionally pin-equivalent because the ADM213E includes shutdown and enable control pins that the ADM211 does not. Designers must verify the pin functions against the respective Analog Devices datasheets before considering any board-level substitution.
What data rate do the ADM213EARSZ and ADM211ARS-REEL support?
Both the ADM213EARSZ and ADM211ARS-REEL are specified for a minimum data rate of 120 kbps, which is the standard rate for the ADM2xx family of 5 V RS-232 transceivers from Analog Devices.
Do both parts operate from a single 5 V supply?
Yes. Both the ADM213EARSZ and ADM211ARS-REEL operate from a single +5 V supply and use on-chip charge pumps to generate the RS-232-compliant positive and negative output voltages required for the transmitter outputs.
How many drivers and receivers do the ADM213EARSZ and ADM211ARS-REEL integrate?
Both devices integrate two RS-232 drivers and two RS-232 receivers, making them dual-channel transceivers suitable for applications requiring two serial communication lines.
What is the significance of the "REEL" suffix on the ADM211ARS-REEL?
The "REEL" suffix indicates that the ADM211ARS-REEL is supplied in tape-and-reel packaging, which is intended for automated pick-and-place assembly lines. The ADM213EARSZ is supplied in standard tube or tray packaging. The electrical specifications of the two parts are otherwise defined by their respective datasheets.
Can the ADM213EARSZ be used as a drop-in replacement for the ADM211ARS-REEL?
Not as a direct drop-in replacement without design review. Although both are 28-lead SSOP dual RS-232 transceivers, the ADM213EARSZ includes shutdown and enable control functions that the ADM211ARS-REEL does not. The additional control pins and their required logic states must be validated against the target design and the Analog Devices datasheets before substitution.
What are the typical applications for the ADM213EARSZ and ADM211ARS-REEL?
Both devices are used in applications requiring dual RS-232 serial interfaces operating from a single 5 V supply, such as portable instruments, notebook and handheld computers, and industrial control equipment. The ADM213EARSZ's shutdown feature makes it suitable for power-sensitive designs, while the ADM211ARS-REEL's tape-and-reel packaging suits high-volume automated assembly.
