Dual D Positive-Edge-Triggered Flip-Flop
with Preset and Clear
General Description
The DM74ALS74A contains two independent positive
edge-triggered flip-flops. Each flip-flop has individual D,
clock, clear and preset 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 LOW
level, the D input signal has no effect.
Asynchronous preset and clear inputs will set or clear Q
output respectively upon the application of low level signal.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
