DC Electrical Characteristics
(SOIC Package)
Note 5:
Max number of outputs defined as (n). n-1 data inputs are driven 0V to 3V. One output at LOW. Guaranteed, but not tested.
Note 6:
Max number of data inputs (n) switching. n-1 inputs switching 0V to 3V. Input-under-test switching: 3V to threshold (V
ILD
), 0V to threshold (V
IHD
).
Guaranteed, but not tested.
Note 7:
Max number of outputs defined as (n). n
1 data inputs are driven 0V to 3V. One output HIGH. Guaranteed, but not tested.
AC Electrical Characteristics
Extended AC Electrical Characteristics
(SOIC Package)
Note 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.).
Note 9:
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 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 250 pF load capacitors in place of the 50 pF load capacitors in the standard AC load.
Note 11:
The 3-STATE delays are dominated by the RC network (500
, 250 pF) on the output and have been excluded from the datasheet.
