Digital optocoupler with lower power supply and high operating temperature (125°C).

 

Key features

  • Operating Temperature : –40°C to +125°C
  • 2.5V/3.3V CMOS compatible
  • Low Power IDD : 1.5mA max
  • Propagation delay (tp) : 90ns max

 

Additional features


The ACPL-M61M optocoupler combines an LED and integrated high gain photo detector to address low power consumption and high operating temperature needs. It supports a 2.5V/3.3V supply voltage with guaranteed AC and DC operational parameters at the full industrial temperature range of –40°C to 125°C. The higher operating temperature helps minimize thermal runway and reduce temperature related design margins. The optocoupler consumes low power LED driving current from 1.6mA and is able to reduce the external driving buffer. This addresses market trends of energy saving efficiency and withstand harsh industrial operating conditions.
