PRELIMINARY DATA
ACNT-H61L
Low Power 10 MBd Digital CMOS Optocoupler
in 14.2 mm Creepage/Clearance Stretched SO8 Package
Product Brief - Preliminary
Description
The ACNT-H61L is a stretched wide optically coupled op-
tocoupler that combines an AlGaAs light-emitting diode
and an integrated high gain photo detector to address
low power need for isolated interface. The optocoupler
consumes extremely low power, at maximum 2 mA across
temperature. The LED forward current operates from 5
mA.
This optocoupler supports both 3.3 V and 5 V supply volt-
age 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 specication of 20 kV/µs.
ACNT-H61L of 14.2 mm creepage/clearance and high volt-
age insulation capability suit for isolated communicate
logic interface and control in high-voltage power sys-
tems such as 690 V
AC
drives, renewable inverters, medical
equipment.
