Note:
1. Data inputs must be low for a minimum time of t
max, after which RESETB is taken high.
2. Data and clock inputs must be held at valid levels (not floating) for a minimum time of t

max after which RESETB is taken low.
3. For data signal input slew rate >=V/ns
4. For data signal input slew rate >=0.5 V/ns and < 1V/ns
5. CLK,CLKB signals input slew rates are >=1V/ns
