Table 1. Input/Output Functional Description
Symbol I/O Type
Polarity Function
RxD Output
Active
Low
This output indicates received serial data. It is a push-pull CMOS driver capable of driv-
ing a standard CMOS or TTL load. No external pull-up or pull-down resistor is required.
This output may switch indeterminately when the module is transmitting. This output pin
is in tri-state mode when the module is in shutdown mode and during digital serial pro-
gramming operations. RxD is high at initializaton.
TxD Input
Active
High
This CMOS input is used to transmit serial data when SD/ Mode is low. An on-chip pro-
tection circuit disables the LED driver if the TxDpin is asserted for longer than 60 µs.
When used in conjunction with the SD/ Mode pin. TxD is low at initializaton.
SD/ Mode Input
Active
High
Assertion of this pin high for a period of time exceeding 400 µs places the module into
shutdown mode. On the falling edge of this signal, the state of the TxDpin is sampled and
used to set receiver low bandwidth (TxD= Low) or high bandwidth (TxD= High) mode.
See Figures 7 and 8 for timings. SD is low at initializaton

Connect to positive power supply (2.7 V to 5.25 V). Placement of a 1.0 µF to 10.0 µF de-
coupling ceramic capacitor as close as possible to the VCC pin is recommended.
Connect to power supply ground. A solid ground plane is recommended.
NC No Connect
- This pin could be connected to ground.

Input
Output
- This pin can be connected directly to VCC. No series resistor is required.
- LED cathode. Leave this pin unconnected. This pin may be monitored to determine the
state of the LED.
