Setting to the Lower Bandwidth Mode

(2.4 kbit/s to 115.2 kbit/s)

1. Set SD/MODE input to logic “HIGH”.

2. Set Txd input to logic “LOW”. Wait ts ≥ 200 ns.

3. Set SD/MODE to logic “LOW” (this negative edge

latches state of Txd, which determines speed

setting).

4. Txd must be held for th ≥ 200 ns.

Txd is now enabled as normal Txd input for the lower

bandwidth mode.

Recommended SMD Pad Layout

The leads of the device should be soldered in the center position of the pads.
