150 Mbps isolation without optocoupler trade-offs
The Texas Instruments ISO7241MDWG4 is a 4-channel, unidirectional digital isolator using capacitive coupling to pass signals across a 2500 Vrms isolation barrier. Three channels drive from Side 1 to Side 2, one channel goes the opposite direction — a 3/1 input split that suits mixed-direction interfaces without external direction logic.
Wide supply and temp envelope for industrial rails
Common-mode transient immunity of 25 kV/µs minimum ensures the data link stays intact during motor drive switching or relay contact bounce.
Package and mounting — 16-SOIC wide-body
Housed in a 16-SOIC wide-body (7.50 mm width) package, surface-mount. The wide body gives the creepage distance needed for 2500 Vrms reinforced isolation. Ships in Tube.
Lifecycle and compliance
The base part number is ISO7241. RoHS compliance is standard for this TI family (no explicit exemption noted).
