PAD FUNCTION

Symbol

Pad No.

Function

6

Power pad. Apply a voltage of 5 V

± 10 %. Connect an external smoothing filter if noise on power line

is high.

GND1

7

GND pad (for output transistor)

GND2

8

GND pad (for circuits excluding output transistor)

IN

9

Input pad. Internal impedance is 190 k

Ω TYP. PIN photodiode can be directly connected.

OUT

5

Output pad. Open-collector output with pull-up resistor (22 k

Ω TYP.) To connect pull-up resistor, use

resistor of 10 k

Ω or higher.
