The SY10/100EL51 are differential clock D flip-flops
with reset. These devices are functionally similar to the
E151 devices, with higher performance capabilities. With
propagation delays and output transition times
significantly faster than the E151, the EL51 is ideally
suited for those applications which require the ultimate
in AC performance.
The reset input is an asynchronous, level triggered
signal. Data enters the master portion of the flip-flop
when the clock is LOW and is transferred to the slave,
and thus the outputs, upon a positive transition of the
clock. The differential clock inputs of the EL51 allow the
device to be used as a negative edge triggered flip-flop.
The differential input employs clamp circuitry to
maintain stability under open input (pulled down to V
EE
)
conditions.

NOTES:
1. Minimum input swing for which AC parameters are guaranteed.
2. The CMR range is referenced to the most positive side of the differential input signal. Normal operation is obtained if the HIGH level falls within the specified
range and the peak-to-peak voltage lies between V
PP
min. and 1V. The lower end of the CMR range is dependent on V
EE
and is equal to V
EE
+ 3.0V.
