device–under–test can be often be driven into a metastable state. If
the Q output is then used to trigger a digital scope set to infinite
persistence the Q output will build a waveform.0 An experiment was
run by continuously operating the devices in the region where
metastability will occur.

When the device–under–test is a 74F74 (which was not designed
with metastable immune characteristics) the waveform will appear
as in Fig. 2.
Fig. 2 shows clearly that the Q output can vary in time with respect
to the Q trigger point. This also implies that the Q or Q output
waveshapes may be distorted. This can be verified on an analog
scope with a charge plate CRT. Perhaps of even greater interest are
the dots running along the 3.5V volt line in the upper right hand
quadrant. These show that the Q output did not change state even
though the Q output glitched to at least 1.5 volts, the trigger point of
the scope.

manifestation of the event will be an increased clock–to–Q/Q

The 74F50109 is a dual positive edge-triggered JK-type flip-flop

The metastability characteristics of the 74F5074 and related part
types represent state–of–the–art TTL technology.
Set (SD) and reset (RD) are asynchronous active low inputs and
operate independently of the clock (CP) input.
After determining the T and t of the flop, calculating the mean time
0
The J and K are edge–triggered inputs which control the state
changes of the flip–flops as described in the function table.
The J and K inputs must be stable just one setup time prior to the
between failures (MTBF) is simple. Suppose a designer wants to
use the 74F50729 for synchronizing asynchronous data that is
arriving at 10MHz (as measured by a frequency counter), has a
clock frequency of 50MHz, and has decided that he would like to
sample the output of the 74F50109 10 nanoseconds after the clock
edge. He simply plugs his number into the equation below:
low–to–high transition of the clock for guaranteed propagation
delays. The JK design allows operation as a D flip–flop by tying J
and K inputs together.
The 74F50109 is designed so that the outputs can never display a
metastable state due to setup and hold time violations. If setup time
and hold time are violated the propagation delays may be extended
beyond the specifications but the outputs will not glitch or display a
metastable state. Typical metastability parameters for the 74F50109

METASTABLE IMMUNE CHARACTERISTICS
Philips Semiconductors uses the term ’metastable immune’ to
describe characteristics of some of the products in its FAST family.
Specifically the 74F50XXX family presently consist of 4 products
which displays metastable immune characteristics. This term means
that the outputs will not glitch or display an output anomaly under
any circumstances including setup and hold time violations.

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
