SN74LS76A Datasheet, PDF (1/4 Pages) ON Semiconductor – LOW POWER SCHOTTKY

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 S_D and C_D are LOW, but the output
states are unpredictable if S_D and C_D 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) one setup time prior to the HIGH–to–LOW clock transition
