Description
The Avago ACPL-M71U and ACPL-M72U are high tem-
perature, digital CMOS optocouplers in SOIC-5 packages.
These optocouplers use the latest CMOS IC technology
to achieve outstanding performance and very low power
consumption. All devices operate over the –40°C to 125 °C
temperature range.
The ACPL-M71U uses a high speed LED, and the
ACPL-M72U uses a low current LED for lower power dis-
sipation. The high speed ACPL-M71U featuring a 35 ns
maximum propagation delay (I
F
=10 mA). The ACPL-M72U
optocoupler features very low power. With a low 4 mA
LED drive current, ACPL-M72U typical propagation delay
is 60 ns.
Each digital optocoupler has a CMOS detector IC, an in-
tegrated photodiode, a high speed transimpedance
ampli er, and a voltage comparator with an output
driver.
