† _{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)].
