Description
I/O
Active
Connect IRED anode directly to the power supply (V
CC2
). IRED
current can be decreased by adding a resistor in series between the
power supply and IRED anode. A separate unregulated power
supply can be used at this pin.
IRED Cathode, internally connected to the driver transistor
This Schmitt-Trigger input is used to transmit serial data when SD
is low. An on-chip protection circuit disables the LED driver if the
Txd pin is asserted for longer than 300
μ
s. The input threshold
voltage adapts to and follows the logic voltage swing defined by the
applied V
logic
voltage.
Received Data Output, push-pull CMOS driver output capable of
driving standard CMOS or TTL loads. During transmission the Rxd
output is inactive. No external pull-up or pull-down resistor is
required. Floating with a weak pull-up of 500 k
(typ.) in shutdown
mode. The voltage swing is defined by the applied V
logic

Shutdown. The input threshold voltage adapts to and follows the
logic voltage swing defined by the applied V

voltage.
