LC78211, 78212, 78213
2. DI, CL and CE Timing
Data is read in on the rising edge of CL and latched on the falling edge of CE.
3. Notes on the Reset Pin
The states of the analog switches are undefined when power is first applied. However, it is possible to use the reset
pin to force all switches to the off state by connecting an RC circuit to this pin.
4. Using a CCB Bus with Multiple ICs
The LC78211, LC78212 and LC78213 retain their prior state until they receive data with a matching address.
5. Replacing Earlier Models
Caution is required when replacing an LC7821N, LC7823N and LC7823N with an LC78211, LC78212 and
LC78213, since the S pin threshold levels differ.
6. Handling of Unused Input Pins
We recommend connecting any unused switch pin to V
SS
through a resistor of up to a few 100 k
Ω
to prevent damage
from static electricity.
