LC78211-E

Ordering number : ENA4817A LC78211, 78212, 78213 CMOS LSI Analog Function Switch http://onsemi.com 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.

Setting this pin low will force all switches the off state. I Operation 1. Data Input Procedure The LC78211, LC78212 and LC78213 are controlled by inputting specified data to the CL, DI and CE pins. The input data consists of 12 bits, of which four bits are address and eight bits are data. Bits correspond to the L1 to L8 and R1 to R8 analog switches, and a value of one turns the corresponding switch on, and a value of zero turns it off. 0.........Off 1.........On The address is used when the chip is connected to a shared bus. The data (address) that must be transmitted depends on the S pin and the particular product as shown in the table below.

This is because the LC78213 has two sets of seven (not eight) circuits. No. 4817-5/6 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 VSS through a resistor of up to a few 100 k from static electricity. to prevent damage ORDERING INFORMATION Device LC78211-E Package DIP30SD(400mil) (Pb-Free / Halogen Free) Shipping (Qty / Packing) LC78212-E DIP30SD(400mil) (Pb-Free / Halogen Free) 20 / Fan-Fold LC78213-E DIP30SD(400mil) (Pb-Free / Halogen Free) 20 / Fan-Fold 20 / Fan-Fold ON Semiconductor and the ON logo are registered trademarks of Semiconductor Components Industries, LLC (SCILLC).
