ACNV260E
2mm DTI, 10MBd Digital Optocoupler
Data Sheet
CAUTION: It is advised that normal static precautions be taken in handling and assembly
of this component to prevent damage and/or degradation which may be induced by ESD.
Description
The new ACNV260E is an optically coupled gate that
combines a AlGaAs light emitting diode and an inte-
grated photo detector housed in a widebody package.
ACNV260E is designed and manufactured to comply
with EN60079-11 ATEX and IECEx. The distance-through-
insulation (DTI) between the emitting diode and photo-
detector is at 2mm. The output of the detector IC is an
open collector Schottky clamped transistor. The internal
shield provides a guaranteed common mode transient
immunity specication of 20,000 V/μs at V
cm
= 1500V
This unique design provides maximum ac and dc circuit
isolation while achieving TTL compatibility.
The new ACNV260E is suitable for high speed logic inter-
facing, input/output buering, as line receivers in envi-
ronments that conventional line receivers cannot tolerate
and are recommended for use in extremely high ground
or induced noise environments.
