The 1 Mbps ceiling means this part fits SPI, UART, and general-purpose logic-level isolation up to that speed, but it will not handle 10/100 Mbps Ethernet or high-speed serial links like CAN FD at 5 Mbps. The 4000 Vpk isolation is a basic insulation rating suitable for industrial equipment with reinforced isolation requirements when combined with proper PCB creepage; it is not a medical-grade 5 kV or 8 kV rating. The 4/0 channel configuration (all four inputs on side 1, all outputs on side 2) makes it a straightforward downstream isolator for a microcontroller's digital outputs to a motor drive or sensor interface. ## Supply voltage flexibility and temperature range The 16-SOIC wide-body package (0.295\" width, 7.50 mm) provides the creepage distance needed to sustain the 4000 Vpk isolation rating across the barrier. ## Propagation delay and CMTI — the real-world timing specs Maximum propagation delay of 95 ns (both directions) and pulse-width distortion of 10 ns are typical for a 1 Mbps capacitive isolator. The 25 kV/µs minimum common-mode transient immunity (CMTI) is the spec that matters in noisy environments: a motor-drive inverter with fast IGBT switching edges can couple several kV/µs across the barrier, and this part's CMTI floor ensures the output does not glitch. The 2 ns typical rise/fall time is fast enough for 1 Mbps signaling but adds some edge-rate energy; keep the trace length short on the output side to avoid ringing. ## Lifecycle and sourcing posture The base product number ISO7240 covers a family of 4-channel isolators with different data rates and channel configurations, so a cross-reference to a faster sibling (e.g., ISO7241 with 25 Mbps) is possible within the same footprint if the design later needs higher speed.","metaTitle":"ISO7240ADWR General Purpose Digital Isolator, 1 Mbps","metaDescription":"TI ISO7240ADWR 4-channel unidirectional digital isolator with capacitive coupling, 1 Mbps data rate, 4000 Vpk isolation, -40°C to 125°C.
