Notes:
1. NC pins are not connected to the die.
2. E3 (DNU) can be left as NC or Vss to ensure proper application.
3. V_IL(min.) = –2.0V for pulse durations less than 20 ns.
4. Typical values are included for reference only and are not guaranteed or tested. Typical values are measured at V_CC = V_CC(typ.) , T _A = 25°C.
