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 kΩ to prevent damage from static electricity. s No products described or contained herein are intended for use in surgical implants, life-support systems, aerospace equipment, nuclear power control systems, vehicles, disaster/crime-prevention equipment and the like, the failure of which may directly or indirectly cause injury, death or property loss. s Anyone purchasing any products described or contained herein for an above-mentioned use shall: x Accept full responsibility and indemnify and defend SANYO ELECTRIC CO., LTD., its affiliates, subsidiaries and distributors and all their officers and employees, jointly and severally, against any and all claims and litigation and all damages, cost and expenses associated with such use:  Not impose any responsibility for any fault or negligence which may be cited in any such claim or litigation on SANYO ELECTRIC CO., LTD., its affiliates, subsidiaries and distributors or any of their officers and employees jointly or severally. s Information (including circuit diagrams and circuit parameters) herein is for example only; it is not guaranteed for volume production.
