All typical values are at VCC = 5 V and TA = 25°C.
Pulse skew is defined as the | td(ODH)–td(ODL)| of each channel.
§ Skew limit is the maximum difference in propagation delay times between any two channels of one device and between any two devices. This
parameter is applicable at one VCC and operating temperature within the recommended operating conditions.
