74LVQ74
Low Voltage Dual D-Type
Positive Edge-Triggered Flip-Flop
General Description
The LVQ74 is a dual D-type flip-flop with Asynchronous
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 (Set) sets Q to HIGH level
LOW input to CD (Clear) sets Q to LOW level
Clear and Set are independent of clock
Simultaneous LOW on CD and SD makes both
Q and Q HIGH
Features
s Ideal for low power/low noise 3.3V applications
s Guaranteed simultaneous switching noise level and
dynamic threshold performance
s Guaranteed pin-to-pin skew AC performance
s Guaranteed incident wave switching into 75Ω
