AC Electrical Characteristics
Note 6: Typical values at VCCA = 3.3V, VCCB = 5.0V @ 25°C.
Note 7: Typical values at VCCA = 3.3V, VCCB = 3.3V @ 25°C.
Note 8: 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.
Capacitance
Note 9: CPD is measured at 10 MHz.
