Dual Positive-Edge-Triggered D Flip-Flops with
Preset, Clear and Complementary Outputs
General Description
This device contains two independent positive-edge-trig-
gered D flip-flops with complementary outputs. The infor-
mation on the D input is accepted by the flip-flops on the
positive going edge of the clock pulse. The triggering
occurs at a voltage level and is not directly related to the
transition time of the rising edge of the clock. The data on
the D input may be changed while the clock is LOW or
HIGH without affecting the outputs as long as the data
setup and hold times are not violated. A low logic level on
the preset or clear inputs will set or reset the outputs
regardless of the logic levels of the other inputs.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
