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 t_s ≥ 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 t_h ≥ 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.
