CASE 620
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.
