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-
ages to this high–impedance circuit. For proper
