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 specification of 20,000 V/

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 buffering, 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.
