The ACPL-M71T are high temperature, digital CMOS optocouplers in SOIC-5 packages. Suitable for hybrid and electric vehicle applications, the optocouplers use the latest CMOS IC technology to achieve outstanding performance and very low power consumption. All devices are AEC-Q100 compliant and operate over the –40°C to 125°C temperature range.The ACPL-M71T uses a high speed LED for lower power dissipation. The high speed ACPL-M71T featuring a 35 ns maximum propagation delay (IF =10 mA). With a low 4 mA LED drive current,.Digital optocoupler has a CMOS detector IC, an integrated photodiode, a high speed transimpedance amplifier, and a voltage comparator with an output driver.The R2Coupler isolation products provide the reinforced insulation and reliability needed for critical in automotive and high temperature industrial applications.
