LED current depends on LED load resistance value.
Include internal current limiter (max.400mA).
NC
This terminal must be left open.
Transmitting Data Input Terminal
H:LED radiant (PWDOWN='L')
CMOS Logic Level Input.
Holding TXD="H"status, LED will be turn off
approximately 48 µs.
Receiving Data Output Terminal
When PWDOWN(5pin)='H', the RXD output will be pulled
up to V

CMOS Logic Level Input.
When input is "H", it will stop the receiving circuit, Pin−PD
current and transmitting LED operation.
V
Supply voltage for Transceiver circuits.
For preventing from infection, connect a capacitor between
