Transceiver I/O Truth Table
The LED and RXD outputs are
controlled by the combination of the
TXD and SD pins and light falling on
the receiver. As shown in the table
below, the transmitter is non-
inverting; the LED is on when the TXD
pin is high and off when TXD is low.

Caution: The BiCMOS inherent to this design of this component increases
the component’s susceptibility to damage from electrostatic discharge
(ESD). It is advised that normal static precautions be taken in handling and
assembly of this component to prevent damage and/or degradation which
may be induced by ESD.

Receiver
The receiver is inverting; the RXD pin
is low during IrDA signal pulses and
high when the receiver does not see
any light. When shutdown (SD pin
high), the LED is off (the state of the
TXD pin does not matter), and the
RXD pin is pulled high with a weak
internal pullup.

Shutdown Mode Notes
When the HSDL-3201 is in Shutdown
Mode (SD pin high), the part presents
different impedances to the rest of the
circuit than when it is in normal mode.
RXD Pin: This pin is NOT Tri-state.
During shutdown the equivalent circuit
is a weak pullup ( ~ 300 k ) to V
ESD protection diodes to V
Ground are also present.
TXD Pin: Input protection diodes are
present.
VLED Pin: Possible leakage current of
1.5 nA.
SD Pin: Will draw approximately 16 nA
when driven high.
Marking Information
The unit is marked with the letter “A”
and “YWWLL” on the shield for front
options where Y is the last digit of the
year, WW is the workweek, and LL is the
lot information. For top options, the
part is marked as “YWW” where Y is the
last digit of the year, and WW is the
workweek.
