Latch & Flip-Flop Characteristic Equations

S-R Latch Qn+1 = S + R'Qn

D latch Qn+1 = D

Edge-triggered D Flip-Flop Qn+1 = D

Master-slave S-R Flip-Flop Qn+1 = S + R'Qn

Master-Slave J-K Flip-Flop Qn+1 = JQn' + K'Qn

Edge-Triggered J-K Flip-Flop Qn+1 = JQn' + K'Qn

T Flip-Flop Qn+1 = Qn'

T Flip-Flop with Enable Qn+1 = EQn' + E'Qn = E Å Qn
