SN74LS76A
Dual JK Flip-Flop with Set and Clear
The SN74LS76A offers individual J, K, Clock Pulse, Direct Set and Direct Clear inputs. These dual flip-flops are designed so that when the clock goes HIGH, the inputs are enabled and data will be accepted. The Logic Level of the J and K inputs will perform according to the Truth Table as long as minimum set-up times are observed. Input data is transferred to the outputs on the HIGH-to-LOW clock transitions.

- Both outputs will be HIGH while both SD and CD are LOW, but the output states are unpredictable if SD and CD go HIGH simultaneously.
H, h = HIGH Voltage Level
L, I = LOW Voltage Level
X = Immaterial l, h (q) = Lower case letters indicate the state of the referenced input i, h (q) = (or output)...
