Dual 5-Input Majority
The MC14530B dual five–input majority logic gate is constructed with
P–channel and N–channel enhancement mode devices in a single
monolithic structure. Combinational and sequential logic expressions are
easily implemented with the majority logic gate, often resulting in fewer
components than obtainable with the more basic gates. This device can also
provide numerous logic functions by using the W and some of the logic (A
thru E) inputs as control inputs.

This device contains protection circuitry to guard against damage
due to high static voltages or electric fields. However, precautions must
be taken to avoid applications of any voltage higher than maximum rated
voltages to this high-impedance circuit. For proper 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.
