CASE 620  
The MC14512B is an 8–channel data selector constructed with MOS  
P–channel and N–channel enhancement mode devices in a single  
monolithic structure. This data selector finds primary application in signal  
multiplexing functions. It may also be used for data routing, digital signal  
switching, signal gating, and number sequence generation.

This device contains protection circuitry to  
guard against damage due to high static  
voltages or electric fields. However, pre-  
cautions must be taken to avoid applications of  
any voltage higher than maximum rated volt-
