Replacement verdict
Compatible functional replacement candidate
The ADM213EARSZ and ADM211ARS are both RS-232 transceivers from Analog Devices in a 28-pin SSOP package, sharing the same supply voltage range and driver/receiver architecture, making the ADM213EARSZ a viable functional replacement candidate for the ADM211ARS. However, the ADM213EARSZ integrates on-chip charge pump capacitors while the ADM211ARS requires external capacitors, so the replacement is not a direct drop-in and the surrounding circuit must be reviewed before substitution.

Frequently asked questions
What are the key differences between the ADM213EARSZ and ADM211ARS?
Both are RS-232 transceivers from Analog Devices in a 28-lead SSOP package, but they differ in driver/receiver count and internal charge-pump configuration. The ADM213EARSZ integrates four drivers and five receivers with a 0.1 µF external capacitor charge pump, while the ADM211ARS provides four drivers and five receivers with a 1 µF capacitor charge pump. The ADM213EARSZ is specified for +5 V operation with a shutdown feature, whereas the ADM211ARS is a +5 V device without the enhanced ESD and shutdown options of the E-series.
Are the ADM213EARSZ and ADM211ARS pin-compatible?
Both devices are offered in the same 28-lead SSOP (RS-28) package, and their pinouts follow the standard ADM2xx family RS-232 transceiver layout. However, designers should verify the exact pin function assignments against the respective datasheets before substituting, because the E-series variant may differ in enable/shutdown pin behavior.
What supply voltage do the ADM213EARSZ and ADM211ARS require?
Both devices operate from a single +5 V ±10% supply (4.5 V to 5.5 V). They use internal charge-pump converters to generate the positive and negative RS-232 output levels from the single supply rail.
How many drivers and receivers does each device provide?
The ADM213EARSZ provides four RS-232 drivers and five RS-232 receivers. The ADM211ARS also provides four drivers and five receivers. Both are therefore suitable for full-duplex plus handshake signal applications such as DTE/DCE interfaces.
What is the difference in external charge-pump capacitors between the two parts?
The ADM213EARSZ is designed for 0.1 µF charge-pump capacitors, which reduces board space. The ADM211ARS uses 1 µF charge-pump capacitors. The capacitor value must match the device datasheet; substituting a different value can affect output voltage levels and RS-232 compliance.
Do both devices support shutdown or standby modes?
The ADM213EARSZ includes a shutdown feature that reduces supply current when the transceiver is not in use. The ADM211ARS does not provide the same shutdown capability. Designers requiring low-power standby operation should confirm the specific shutdown pin and current specifications in the respective datasheets.
What data rate can the ADM213EARSZ and ADM211ARS support?
Both devices are specified for RS-232 data rates up to 120 kbps, which is sufficient for standard serial communication interfaces. The actual achievable rate depends on cable length, capacitive load, and the external charge-pump capacitor values specified for each device.
Can the ADM213EARSZ be used as a drop-in replacement for the ADM211ARS?
Not unconditionally. Although both are 28-lead SSOP RS-232 transceivers with four drivers and five receivers, the charge-pump capacitor values (0.1 µF vs 1 µF) and the shutdown feature differ. A replacement should only be made after verifying pin functions, capacitor values, and shutdown behavior against the manufacturer datasheets for the target design.
