T-flip flop has the following feature:
On each successive input, Q and
Q
outputs toggle (complements their previous states).
14.4.1 T Flip-Flop with Clear and Preset
T-flip flop with clear and preset is a circuit in Figure 14.6(a) with R and S inputs provided to
a user of the T-FF as the additional inputs. If inputs are given at the points R and/or S in
Figure 14.6(a) circuit, then the circuit shall respond with a priority to the changes at these
inputs. For example, if S input is activated and made 0, the output
Q
shall stay 1. No matter
what are the states occurring at the T-input. The S input and R input are, therefore, ...
