AC Electrical Characteristics for ACQ
Note 13: Voltage Range 5.0 is 5.0V
± 0.5V
Voltage Range 3.3 is 3.3V
± 0.3V
Note 14: Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device. The
specification applies to any outputs switching in the same direction, either HIGH-to-LOW (tOSHL) or LOW-to-HIGH (tOSLH). Parameter guaranteed by design.
