MC14512B
8-Channel Data Selector
The MC14512B is an 8âchannel data selector constructed with MOS
Pâchannel and Nâchannel 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 highâimpedance circuit. For proper
v v operation, Vin and Vout should be constrained
to the range VSS (Vin or Vout) VDD.
Unused inputs must always be tied to an
appropriate logic voltage level (e.g., either VSS
or VDD). Unused outputs must be left open.
