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

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

amplifier, and a voltage comparator with an output

driver.

motive and high temperature industrial applications
