BNS-OD-C131/A4
DESCRIPTION
These diode-transistor photocouplers
consist of an AlGaAs LED optically
coupled to a high speed photodetector.
The output features is an open collector
and coupler parameters are guaranteed
over the temperature range from
-40℃~85℃. The internal shield
provides a guaranteed Common Mode
Transient Immunity (typical) 10KV/μs
FEATURES
* High speed – 10MBd
* Common mode rejection - 10KV/μs
* UL, CSA, IEC/EN/DIN EN60747-5-2 –
