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.

NOTES:
1
For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type.
2
All typical values are at V
CC
= 5V, T
amb
= 25
C.
3
Not more than one output should be shorted at a time. For testing I
OS
, the use of high-speed test apparatus and/or sample-and-hold
techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting
of a high output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any
sequence of parameter tests, I
OS
tests should be performed last.
4
Measure I
CC
with the clock input grounded and all outputs open, then with Q and Q outputs high in turn.
