Description
I/O
Active
Connect IRED anode directly to V
CC2
. For voltages higher than 3.6 V an
external resistor might be necessary for reducing the internal power
dissipation.An unregulated separate power supply can be used at this pin.
IRED cathode, internally connected to driver transistor
This 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 80
μ
s. When used in conjunction with the SD pin, this pin is also used to
receiver speed mode.
Received Data Output, push-pull CMOS driver output capable of driving a
standard CMOS or TTL load. No external pull-up or pull-down resistor is
required.
Floating with a weak pull-up of 500 k
(typ.) in shutdown
mode.
Shutdown, also used for dynamic mode switching. Setting this pin active
places the module into shutdown mode. On the falling edge of this signal, the
state of the Txd pin is sampled and used to set receiver low bandwidth (Txd
= Low, SIR) or high bandwidth (Txd = High, MIR and FIR) mode. Will be
overwritten by the mode pin input, which must float, when dynamic
programming is used.

Output function: The mode pin can also be used to indicate the dynamically
programmed mode. The maximum load is limited to 50 pF. High indicates
MIR-, low indicates SIR-mode
