Best Alternatives to ISO3088DWR

Package: 16-SOIC (0.295", 7.50mm Width)Texas InstrumentsDriversPackage: Tape & Reel (TR); Cut Tape (CT); Digi-Reel®Type: Transceiver, IsolatedData Rate: 20MbpsVoltage - Supply: 3.15V ~ 5.5V, 4.5V ~ 5.5VOperating Temperature: -40°C~85°C

ISO3088DWR is an isolated 20Mbps RS-485/RS-422 transceiver in a SOIC-16 package. Alternatives exist from the same manufacturer but require careful review of data rate and pin compatibility.

AI replacement insight

Electrical riskmedium

Data rate is lower on all viable alternatives.

Package risklow

Package is identical (SOIC-16), but pinout needs verification.

Firmware risklow

Protocol is the same; no firmware changes likely needed unless timing is critical.

Can it be replaced directly?

Direct replacement for ISO3088DWR should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

ISO1430BDWR offers a good balance of features but at a lower speed (12Mbps).

Main risk

The primary risk is a reduction in data rate, which could impact system performance if the full 20Mbps is required.
