■ GENERAL DESCRIPTIONS

The circuit consists of a photodiode, amplified circuit, a decision circuit

(schmidt trigger circuit) and an output buffer circuit. When the light comes,

the circuit will sense the signal and give a corresponding output signal.

PS103C/104C will generate a digital signal off/on corresponding to the incoming

light which is on/off. The output buffer will give a TTL compatible output

signal from the digital signal. With build-in regulator, this circuit has

a wide operation range.
