8-PIN WIDE BODY, HIGH-SPEED
OPTOCOUPLERS
CNW135
DESCRIPTION
The CNW135, CNW136 and CNW4502 are fast-switching optocouplers, consisting
of an AlGaAs LED optically coupled to a high speed photodetector transistor in a
wide 8-pin dual-in-line (DIL) plastic envelope.
The CNW4502 provides the same electrical switching and isolation performances as
the CNW136, and increased ESD protection due to a non-connected base.
