DESCRIPTION
This device incorporates an integral photodiode, amplifier, Schmitt trigger, and internally pulled-up output stage. An on-chip voltage regulator allows operation over a wide range of available supply voltage. The phase of the digital output is considered to be inverted from the optical input, so that the output is HI when the light source is OFF, and...
