DC CHARACTERISTICS

VSS =0 V

Note

1. All inputs at 0 V or VDD; except input AR = input MR = 0 V (power-on reset active).

AC CHARACTERISTICS

VSS = 0 V; Tamb =25 °C; input transition times ≤ 20 ns

Notes

1. where:

fi

= input frequency (MHz)

fo

= output frequency (MHz)

CL

= load capacitance (pF)

VDD = supply voltage (V)

Ct

= timing capacitance (pF)
