Electrical characteristics

7/15

Note:

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.

2tsk(P) is the magnitude difference in differential propagation delay time between the positive

going edge and the negative going edge of the same channel.

3tsk(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.

(Over recommended operating conditions unless otherwise noted. All typical values are at

TA = 25°C, and VCC = 3.3V).
