Extended AC Electrical Characteristics

(SOIC Package)

Note 9: 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.).

Note 10: This specification is guaranteed but not tested. The limits represent propagation delay with 250 pF load capacitors in place of the 50 pF load capac-

itors in the standard AC load. This specification pertains to single output switching only.

Note 11: 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 250 pF load capacitors in place of the 50 pF load capacitors in the standard AC load.

Note 12: The 3-STATE delay Time is dominated by the RC network (500

:, 250 pF) on the output and has been excluded from the datasheet.

Note 13: This specification is guaranteed but not tested. The limits represent propagation delays with 250 pF load capacitors in place of the 50 pF load

capacitors in the standard AC load.

Note 14: This describes the difference between the delay of the LOW-to-HIGH and the HIGH-to-LOW transition on the same pin. It is measured across all

the outputs (drivers) on the same chip, the worst (largest delta) number is the guaranteed specification. This specification is guaranteed but not tested.

Note 15: Skew is defined as the absolute value of the difference between the actual propagation delays for any two separate outputs of the same device.

tested.

Note 17: 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.).
