SWITCHING CHARACTERISTICS

(TA = -40 °C to +85 °C; VA+ = 5.0 V ±10%; VD+ = 3.0 V ±10% or 5.0 V ±10%; VA- = 0.0 V; Logic Levels:

Logic 0 = 0.0 V, Logic 1 = VD+; CL = 50 pF))

Notes: 24. Device parameters are specified with a 4.096 MHz clock, yet, clocks between 3 MHz to 20 MHz can be

used. However, for input frequencies over 5 MHz, an external oscillator must be used.

25. If external MCLK is used, then duty cycle must be between 45% and 55% to maintain this specification.

26. Specified using 10% and 90% points on wave-form of interest. Output loaded with 50 pF.

27. Oscillator start-up time varies with crystal parameters. This specification does not apply when using an

external clock source.
