General Description
The LCX74 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
