SWITCHING CHARACTERISTICS (Unless otherwise noted. Typical values are referred to TA =25°C

and VCC =3.3V)

Note 1: tsk(O) is the maximum delay time difference between the propagation delay of one channel and that of the others on the same chip

with any event on the inputs.

Note 2: tsk(P) is the magnitude difference in differential propagation delay time between the positive going edge and the negative going edge

of the same channel.

Note 3: tsk(PP) is the differential channel-to-channel skew of any event between devices. This specification applies to devices at the same

VCC, and within 5°C of each other within the operating temperature range.
