The 16-SOIC package (7.50mm body width) supports surface-mount assembly on standard automotive PCB stacks. ## Supply flexibility: 2.25V to 5.5V on both sides Both isolation domains accept 2.25V to 5.5V independently, so a 3.3V MCU on side 1 can talk to a 5V peripheral on side 2 without a separate level shifter. The 16ns propagation delay is symmetric (tpLH = tpHL), which keeps the duty cycle within 4.9ns distortion — important for PWM signals where pulse-width accuracy matters. The 16-SOIC wide-body (7.50mm width) provides 8mm creepage distance minimum for reinforced isolation in 1000Vrms working-voltage systems. The 16-SOIC supplier device package matches the standard automotive-grade footprint used across TI's ISO77xx family, so a layout designed for the ISO7741 or ISO7730 accepts this part without board changes.","metaTitle":"TI ISO7740QDWQ1 Digital Isolator, 5000Vrms, AEC-Q100","metaDescription":"TI ISO7740QDWQ1 automotive-grade digital isolator, 4 unidirectional channels, 5000Vrms isolation, 100Mbps data rate, -40°C to 125°C.

The ISO7741 uses a 3/1 input configuration: three channels forward (side 1 to side 2) and one channel reverse (side 2 to side 1). Both parts share the same 100Mbps data rate, 5000Vrms isolation, 16ns propagation delay, and AEC-Q100 qualification. Choose the ISO7740 when all four isolation channels carry data in one direction; choose the ISO7741 when one channel needs to return a status signal or acknowledge from the isolated side."},{"question":"Can I use ISO7740QDWQ1 in a non-automotive design?","answer":"Yes. The AEC-Q100 qualification does not prevent use in industrial or commercial designs — it simply guarantees the part has passed automotive-grade stress testing. The automotive-grade suffix (Q1) typically carries a small cost premium over the commercial-grade variant, so if volume is high and automotive qualification is not needed, compare the non-Q1 ISO7740DW part."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/ISO7740QDWQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/ISO7740QDWQ1 when reusing this data.
