Skew
(SOIC Package)
Note 14:
Skew is defined as the absolute value of the difference between the actual propagation delays for any two separate outputs of the same device.
The specification applies to any outputs switching HIGH to LOW (t
OSHL
), LOW-to-HIGH (t
OSLH
), or any combination switching LOW-to-HIGH and/or HIGH-to-
LOW (t
OST
). This specification is guaranteed but not tested.
Note 15:
Propagation delay variation for a given set of conditions (i.e., temperature and V
CC
) from device to device. This specification is guaranteed but not
tested
Note 16:
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 17:
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 18:
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.
Capacitance

C
I/O
is measured at frequency, f
=
1 MHz, per MIL-STD-883D, Method 3012.
