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