DM7474
Dual Positive-Edge-Triggered D-Type Flip-Flops with
Preset, Clear and Complementary Outputs
General Description
This device contains two independent positive-edge-trig-
gered D-type flip-flops with complementary outputs. The
information 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.

H
= HIGH Logic Level
X
= Either LOW or HIGH Logic Level
L
= LOW Logic Level
↑ = Positive-going transition of the clock.
Q0 = The output logic level of Q before the indicated input conditions were
established.
Note 1: This configuration is nonstable; that is, it will not persist when either
the preset and/or clear inputs return to their inactive (HIGH) level.
