SN74LS74A
Dual DType Positive
EdgeTriggered FlipFlop
The SN74LS74A dual edge-triggered flip-flop utilizes Schottky
TTL circuitry to produce high speed D-type flip-flops. Each flip-flop
has individual clear and set inputs, and also complementary Q and Q
outputs.
Information at input D is transferred to the Q output on the
positive-going edge of the clock pulse. Clock triggering occurs at a
voltage level of the clock pulse and is not directly related to the
transition time of the positive-going pulse. When the clock input is at
either the HIGH or the LOW level, the D input signal has no effect.

* 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. If the levels
at the set and clear are near VIL maximum then we cannot guarantee to meet
the minimum level for VOH.

L, I = LOW Voltage Level

l, h (q) = Lower case letters indicate the state of the referenced input
i, h (q) = (or output) one set-up time prior to the HIGH to LOW clock transition.
