CMOS IC
DESCRIPTION
The U74LCX74 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. 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
* 2.3V-3.6V VCC specifications provided
* 5V tolerant inputs
* 7.0 ns tPD max (VCC=3.3V), ICC=10μA (max.)
* Power down high impedance inputs and outputs
* ±24mA output drive (VCC=3.0V)
