Description
The Avago ACPL-M71T and ACPL-M72T are high tem-
perature, 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, and the ACPL-M72T
uses a low current LED for lower power dissipation. The
high speed ACPL-M71T featuring a 35 ns maximum
propagation delay (I
F
=10 mA). The ACPL-M72T optocou-
pler features very low power. With a low 4 mA LED drive
current, ACPL-M72T typical propagation delay is 60 ns.
Each digital optocoupler has a CMOS detector IC, an in-
tegrated photodiode, a high speed transimpedance
amplier, and a voltage comparator with an output
driver.
