Pin1 and pin4 must be connected to the
ground.
This Terminal must be left open.
V
For preventing from infection, connect
a capacitor between V
GND (4pin).
Power-down Control Terminal
H : POWERDOWN
L : OPERATION
CMOS Logic Level Input
When input is H, it will stop the receiving
circuit, Pin-PD current and transmitting
LED operation.
Receiving Data Output Terminal
CMOS Logic Level Output
When PWDOWN (5pin)=H, the RXD
output will be pulled up to V
approximately 300kΩ.
Transmitting Data Input Terminal
H : LED (PWDOWN=L)
CMOS Logic Level Input
Holding TXD="H" status, LED will be
turn off approximately 45µs.
Connect to Ground.
LED ANODE Terminal
Other power source can be used
difference between LEDV
LED current depends on LED load
resistance value.
