DESCRIPTION

The H11AA1 is a bi-directional input optically coupled

isolator consisting of two inverse parallel gallium arsenide

infrared LEDs coupled to a silicon NPN phototransistor in a

6 pin DIP package. The H11AA1 has a minimum CTR of

20 , a CTR symmetry of 1:3 and is designed for

applications requiring detection or monitoring of AC signals.
