1) The DC values define where the input slew rate requirements are imposed, and the input signal must not violate these levels in order to
2) Input slew rate = 3 V/ns. If the input slew rate is less than 3 V/ns, input timing may be compromised. All slew rates are measured between
3)
4) The MF pin must be hard-wired on board to either
