DESCRIPTION
The 74LVT74 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.
