NOTES:
1. Data inputs must be low a minimum time of tACT max., after RESET is taken HIGH.
2. Data and clock inputs must be held at valid levels (not floating) a minimum time of tINACT max., after RESET is taken LOW.
3. For data signal input slew rate is ≥1V/ns.
4. For data signal input slew rate is ≥0.5V/ns and <1V/ns.
5. CLK, CLK signal input slew rates are ≥1V/ns.
