† tsk(t) − Output-to-output skew is defined as the absolute value of the difference between the actual propagation delay for all outputs of the same

packaged device. The specifications are given for specific worst-case VCC and temperature and apply to any outputs switching in opposite

directions, both low to high (LH) and high to low (HL) [tsk(t)].
