74F74
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
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
