Zarlink Semiconductor Inc.
Characteristics are over recommended operating conditions unless otherwise stated.
Typical figures are at 25°C, VDD_CORE at 1.8 V and VDD_IO at 3.3 V and are for design aid only: not guaranteed and not subject to produc-
tion testing.
* Test condition is R
= 1 k, C
L
= 30 pF; high impedance is measured by pulling to the appropriate rail with R
L
, with timing corrected to cancel
the time taken to discharge C
L
.
