Power-down control terminal
H : Power down
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 teminal
CMOS logic level output
When PWDOWN (5pin) = H, the RXD output will
be pulled up to V
Transmitting data input terminal
H : LED (PWDOWN = L)
CMOS logic level input
Holding TXD = H status, LED will be
turned off at approximately 48µs.
LED ANODE terminal
Other power source can be used
difference between VLEDA and V
This can be connected to battery kinds of unregulated
voltage source by internal constant current driver.
