Power Supply Terminal
For preventing from infection, connect
a capacitor between V
GND (1pin).
RC Transmitting Data Input Terminal
H : LED Emitting
CMOS Logic Level Input
Holding TX-RC='H' status, LED will be
turn off approximately 48µs.

Intensity switching Terminal
H : POWERDOWN (RC transmitting Mode)
L : OPERATION
CMOS Logic Level Input
When input is 'H', it will stop the receiving
circuit and Pin-PD current.
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
IrDA TXD input at PWDOWN=L
(Remote control transmitting input at PWDOWN=H).
H : LED Emitting
CMOS Logic Level Input
Holding TXD="H" status, LED will be
turn off approximately 48µs.
LED ANODE Terminal
Other power source can be used
difference between LEDV
LED current depends on LED load
resistance value at RC mode.
