Applications
Function switching under serial data control in amplifiers, receivers, and other electronic equipment.
Features
Two sets of eight (or in the LC78213, seven) built-in circuits with three switching configurations available based on
differing internal connections.
Control according to serial data sent from a microprocessor, and easy connection to 5 V microprocessors.
Two identical products can be connected to a shared bus due to the provision of a select pin (S).
A reset pin that turns off all analog switches.
A ±20 V withstand voltage rating allows these products to provide a wide dynamic range.

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed,
damage may occur and reliability may be affected.

2. DI, CL and CE Timing
LC78211, 78212, 78213
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 VSS through a resistor of up to a few 100 k to prevent damage
from static electricity.
