Flip-flops are the essential building blocks of any counter circuit. In this design counter consist of a layout design of transmission gate base latch circuit connected in master slave arrangement. In this paper, the authors design a frequency divider counter design by pass transistor logic circuit technique. Transmission gate can be act as a switch with low resistance and capacitance having the ratio less logic and the DC characteristic of this gate are independent of the input levels. The proposed counter is a 3 bit pass transistor base counter, which chain through a fixed set of pre assigned count states, of which each next count state represents the next counter value in sequence.
