Notes:
8. This specification is guaranteed but not tested. The limits apply to propagation delays for all paths described
9. This specification is guaranteed but not tested. The limits represent propagation delay with 250pF load capacitors
10. This specification is guaranteed but not tested. The limits represent propagation delays for all paths described
11. The 3-STATE delay Time is dominated by the RC network (500Ω, 250pF) on the output and has been excluded from
