Overview
The Broadcom ACPL-K74T-000E is a dual-channel automotive-grade digital optocoupler featuring logic outputs. It operates within a temperature range of -40°C to +125°C and provides 5000Vrms isolation voltage. Key electrical parameters include a typical rise/fall time of 10ns, a maximum forward current of 10mA, and a forward voltage of 1.5V. The device supports a continuous output current of 10mA with a power dissipation of 40mW. It is housed in an 8-pin SOIC stretched package and complies with AEC-Q100 standards.
Feature Summary
- High-speed signal transmission with 10ns rise and fall times for efficient data integrity.
- Automotive qualification ensuring reliability under extreme thermal conditions up to 125°C.
- Robust galvanic isolation capability to protect sensitive control circuits from high voltage transients.
Applications
- Automotive engine control units requiring isolated digital communication.
- Inverter gate drive circuits in electric vehicle powertrains.
- Battery management systems needing high-speed isolated feedback loops.
Procurement Notes
Verify the specific suffix and tape/reel or tube packaging configuration against the final assembly requirements. Confirm that the AEC-Q100 certification status aligns with the target automotive application's quality standards. Ensure the 8-pin SOIC stretched footprint matches the PCB design constraints before finalizing procurement orders.
Selection Notes
Select this component when high-speed switching and automotive durability are required simultaneously. The dual-channel configuration allows for cost-effective isolation of multiple signals within a compact surface-mount footprint. Consider the 10ns propagation speed for applications demanding minimal latency in digital control loops.
Part Context
This device belongs to the ACPL-K71T/K72T/K74T/K75T family of high-speed low-power digital optocouplers. These components utilize R2Coupler technology to deliver enhanced performance compared to standard optocouplers. The series is specifically engineered to meet the rigorous demands of modern automotive electronic architectures.
Replacement Considerations
Check for direct substitutes within the same ACPL-K74T series variant if pinout compatibility is critical. Verify equivalent isolation voltage and CMTI ratings when considering alternative manufacturers' automotive-grade dual-channel optocouplers.
