3.6 V an external resistor might be necessary for reducing the internal power
Adapted to low i/O voltage 1.8-V logic. Floating with a weak pull-up of 500 kΩ
dissipation. See derating curves. This pin is allowed to be supplied from an
standard CMOS load. No external pull-up or pull-down resistor is required.
Received Data Output, push-pull CMOS driver output capable of driving a
IRED anode to be externally connected to V
uncontrolled power supply separated from the controlled V
(typ.) in shutdown mode. The RXD output echos the TXD input during
Shutdown, also used for dynamic mode switching
