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

typically 4

µs and minimum CTR is

50% at input current of 5 mA.
