6 / 13 page ©1993 Fairchild Semiconductor Corporation www.fairchildsemi.com 74ABT373 Rev. 1.4 6 AC Operating Requirements SOIC and SSOP packages. Extended AC Electrical Characteristics SOIC package. Notes: 7. 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.). 8. 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. 9. 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. 10. The 3-STATE delay times are dominated by the RC network (500 Ω, 250pF) on the output and has been excluded from the datasheet.
