When either output disable M or N is high, the outputs are disabled (high impedance state);
however sequential operation of the flip-flops is not affected. H = High level voltage
L = Low level voltage
τ = Low-to-high transition of the clock
↓ = High-to-low transiton of the clock x = Don't care
Device type 02 and 03
Synchronous operation Asynchronous operation
(S = 0, R = 0) (J and K don't care)
