The MAX14930CASE+ is a four-channel, unidirectional digital isolator using capacitive coupling. It provides 2750Vrms isolation and a 150Mbps data rate.
The 2750Vrms isolation rating covers basic insulation for industrial equipment. The 25kV/µs minimum common-mode transient immunity prevents output glitches during fast ground-plane jumps.
The MAX14930 family includes the MAX14930B and MAX14930C variants with different data rate and isolation ratings. For a higher isolation level, the MAX14932 series offers 5kVrms in a similar SOIC-16 footprint. Verify pinout and supply voltage compatibility before substituting.
Yes, it is ROHS3 compliant.
This part is sourced to order through independent distribution. Submit an RFQ for current pricing and availability; quotes are confirmed at order time.
The 16-SOIC package has four unidirectional channels: inputs on side 1 (pins 1-4), outputs on side 2 (pins 9-12), plus VDD and GND on each side. Pin 8 is the enable pin. The exact pinout is in the datasheet.
