Abstract
Three state latch. In accordance with a first embodiment, an electronic circuit includes n pairs of cascaded logical gates. Each of the n pairs of cascaded logical gates includes a first logical gate including n−1 first gate inputs and one first gate output, and a second logical gate including two second gate inputs and one second gate output. One of the second gate inputs is coupled to the first gate output. The second gate output is cross coupled to one of the first gate inputs of all other the pairs of cascaded logical gates, and n is greater than 2.
