Ground Termianl
Power Supply Terminal
For preventing from infection, connect
a capacitor between VCC (6pin) and
GND (7pin).
Connect to Ground.
RC Transmitting Data Input Terminal
H : LED Emitting (Remote Control Mode)
CMOS Logic Level Input
Holding TX-RC='H' status, LED will be
turn off approximately 48祍.
Power-down Control Terminal
CMOS Logic Level Input
When input is 'H', it will stop the receiving
circuit and Pin-PD current.
H : POWERDOWN
L : OPERATION
Receiving Data Output Terminal
CMOS Logic Level Output
When PWDOWN (5pin)= 'H', the RXD
output will be pulled up to VCC at
approximately 300k&.
Transmitting Data Input Terminal
TXD input at PWDOWN=L
H : LED Emitting
CMOS Logic Level Input
Holding TXD="H" status, LED will be
turn off approximately 48祍.
LED ANODE Terminal
Other power source can be used
difference between LEDVCC and VCC.
