Description
Ordering Information
Specify part number followed by
Option Number (if desired).
The HCPL-181 contains a light
emitting diode optically coupled to
a phototransistor. It is packaged in
a 4-pin mini-flat SMD package with
a 2.0 mm profile. The small
dimension of this product allows
significant space saving. The
package volume is 30% smaller
than that of conventional DIP type.
Input-output isolation voltage is
High collector-emitter voltage (V
=80V)
