NOTES:
1. Parameters are valid over specified temperature range. See Ordering information table for applicable operating temperature range and V
CC
supply range.
2. All voltage measurements are referenced to ground (GND). For testing, all inputs except X1/CLK swing between 0.4V and 2.4V with a
transition time of 20ns maximum. For X1/CLK this swing is between 0.4V and 4.4V. All time measurements are referenced at input voltages
of 0.8V and 2.0V as appropriate.
3. Typical values are at +25
°
C, typical supply voltages, and typical processing parameters.
