Agilent HCPL-181
Phototransistor Optocoupler
SMD Mini-Flat Type
Data Sheet
Description
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
3750 Vrms. Response time, tr, is
typically 4 µs and minimum CTR is
50% at input current of 5 mA.
