Broadcom ACNT-H61L-500E

The ACNT-H61L is a stretched wide optically coupled optocoupler that combines a light-emitting diode and an integrated high gain photo detector to address the low power need for isolated interface. The optocoupler consumes extremely low power, at maximum 2 mA across temperature. The LED forward current operates from 4.5 mA. This optocoupler supports both a 3.3V and a 5V supply voltage with guaranteed AC and DC operational parameters from temperature range -40°C to +105°C. The output of the detector IC is a CMOS output. The internal Faraday shield provides a guaranteed common-mode transient immunity specification of 20 kV/μs. The ACNT-H61L with 15-mm stretched SO-8 package and high voltage insulation capability is suitable for isolated communicate logic interface and control in high-voltage power systems such as 690VAC drives, renewable inverters, and medical equipment.
