AC Operating Requirements

Extended AC Electrical Characteristics

SOIC package.

Notes:

8. This specification is guaranteed but not tested. The limits apply to propagation delays for all paths described

switching in phase (i.e., all LOW-to-HIGH, HIGH-to-LOW, etc.).

9. This specification is guaranteed but not tested. The limits represent propagation delay with 250pF load capacitors

in place of the 50pF load capacitors in the standard AC load. This specification pertains to single output switching

only.

10. This specification is guaranteed but not tested. The limits represent propagation delays for all paths described

switching in phase (i.e., all LOW-to-HIGH, HIGH-to-LOW, etc.) with 250pF load capacitors in place of the 50pF load

capacitors in the standard AC load.

11. The 3-STATE delay Time is dominated by the RC network (500

Ω, 250pF) on the output and has been excluded from

the datasheet.
