Description
The ACPL-M51L (single-channel in SO-5 footprint), is low
power, low supply voltage 1MBd digital optocoupler, con-
figurable as a 4pin device.
This digital optocoupler use an insulating layer between
the light emitting diode and an integrated photon detec-
tor to provide electrical insulation between input and out-
put.
ACPL-M51L has an increased common mode transient im-
munity of 15kV/µs minimum at VCM = 1500V.
The current transfer ratio (CTR) is 140% typical for ACPL-
M51L at IF = 3.0mA. This digital optocoupler can be use in
any TTL/CMOS, TTL/LSTTL or analog applications.
