Product details

Four-channel capacitive isolator for industrial signal paths

The MAX14936FAWE+ is a 4-channel general-purpose digital isolator from Maxim Integrated, built on capacitive coupling technology. It provides 5000 Vrms of galvanic isolation across a 16-SOIC package, with unidirectional channels configured as two inputs on side 1 and two on side 2. The part handles data rates up to 150 Mbps, with typical propagation delays under 7.5 ns and pulse-width distortion held to 1 ns max — tight enough for SPI clock isolation and UART links in motor drives, PLC I/O modules, and industrial sensor interfaces.

Temperature grade and deployment context

Rated for -40°C to 125°C, the MAX14936FAWE+ is suited for outdoor telecom cabinets, factory-floor automation, and under-hood automotive electronics. The surface-mount 16-SOIC (7.50 mm wide) footprint matches standard isolation footprints; no isolated power is generated on-chip.

Frequently asked questions

What is the price of MAX14936FAWE+?

Pricing is confirmed at quote time based on quantity and current market conditions. Request a quote for a firm price on this part.

Is MAX14936FAWE+ equivalent to MAX14935FAWE+?

The MAX14935FAWE+ is a close family sibling — both are 4-channel capacitive isolators in the same 16-SOIC package. The key difference is channel direction: the MAX14936FAWE+ has a 2/2 input/output split, while the MAX14935FAWE+ uses a different channel configuration. Verify the direction count against your signal routing before substituting.

Does MAX14936FAWE+ have any known compatibility issues with 5V systems?

No — the supply range of 1.71 V to 5.5 V on both sides covers 5 V logic directly. The 150 Mbps data rate and 2 ns typical rise/fall times are compatible with 5 V CMOS and TTL levels. No level shifting is needed when bridging a 3.3 V controller to a 5 V peripheral.

Is MAX14936FAWE+ compatible with 3.3V logic?

Yes — the supply range includes 3.3 V, and the unidirectional inputs accept 3.3 V logic levels directly. Propagation delays and pulse-width distortion are specified at the same values across the supply range, so timing margins hold at 3.3 V.
