Dual D-Type Positive Edge-Triggered Flip-Flop
General Description
The ’F74 is a dual D-type flip-flop with Direct Clear and Set
inputs and complementary (Q Q) outputs Information at the
input is transferred to the outputs on the positive 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 After the Clock Pulse input
threshold voltage has been passed the Data input is locked
out and information present will not be transferred to the
outputs until the next rising edge of the Clock Pulse input
Asynchronous Inputs
LOW input to SD sets Q to HIGH level
LOW input to CD sets Q to LOW level
Clear and Set are independent of clock
Simultaneous LOW on CD and SD
makes both Q and Q HIGH
Guaranteed 4000V minimum ESD protection
