Zarlink Semiconductor Inc.
Characteristics are over recommended operating conditions unless otherwise stated.
Typical figures are at 25
°
C and are for design aid only: not guaranteed and not subject to production testing.
* The AC electrical characteristics are listed as a function of the internal timing variation (
) to highlight the value of each parameter independent
of the variation. It is important to choose the maximum or minimum
value correctly for worst case timing calculation. When adding parameters
for timing calculation, it is sufficient to include this
only once in the calculation.
