Receiving Data Output Terminal
CMOS logic level output
When PWDOWN (5pin) = H, the RXD
output will be pulled up to
VIO at approximately 300kΩ.
Transmitting Data Input Terminal
H : LED (PWDOWN = L)
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
This can be connected to battery kinds
of unregulated voltage source by internal
constant current driver.
Connect to Ground.
Power-down Control Terminal
H : POWERDOWN MODE
L : OPERATING MODE
CMOS logic level input
When input is H, it will stop the receiving
circuit, Pin-PD current and transmitting
LED operation.
