ABSTRACT:
A transmission gate circuit 20 includes a pull-up control circuit 15, a pull-down control circuit 17, and an electrical switch 19. Pull-up control circuit 15 and electrical switch 19 provide fast, complete transition from low-to-high at the output of circuit 20 thus improving circuit 20 speed as well as improving the switching speed of subsequent gates. Pull-down control circuit 17 and electrical switch 19 provide complete transition from high-to-low at the output of circuit 20. Transmission gate circuit 17 also provides increased drive such that circuit 20 may provide a gate fanout increase of 3X.
