DESCRIPTION
The 74F74 is a dual positive edge-triggered D-type flip-flop featuring
individual data, clock, set, and reset inputs; also true and
complementary outputs. Set (SD) and reset (RD) are asynchronous
active low inputs and operate independently of the clock input. When
set and reset are inactive (high), data at the D input is transferred to
the Q and Q outputs on the low-to-high transition of the clock. Data
must be stable just one setup time prior to the low-to-high transition of
the clock for predictable operation. Clock triggering occurs at a
voltage level and is not directly related to the transition time of the
positive-going pulse. Following the hold time interval, data at the D
input may be changed without affecting the levels of the output.
