The following conditions apply:
a) Parameters are valid over specified temperature and voltage range.
b) All voltage measurements are referenced to ground. For testing, all inputs swing between 0.4 V and 3.0 V with a transition time of
c) Typical values are at 25 C, typical supply voltages, and typical processing parameters.
Test conditions for outputs: C
constant current source = 2.6 mA.
Input port pins have active pull-up transistors that will source a typical 2 A from V
0.0 A.
All outputs are disconnected. Inputs are switching between CMOS levels of V
5 ns maximum. For X1/CLK this swing is between 0.4 V and 0.8V
and 2.0 V, and output voltages of 0.8 V and 2.0 V, as appropriate.
