SWITCHING CHARACTERISTICS
(VA+ = 2.5 V or 5 V ±5%; VA- = -2.5V±5% or 0 V; VD+ = 3.0 V ±10% or 5 V ±5%;DGND = 0 V;
Levels: Logic 0 = 0 V, Logic 1 = VD+; C
L
= 50 pF; See Figures 1 and 2.)
Notes: 26. Device parameters are specified with a 4.9152 MHz clock.
27. Specified using 10% and 90% points on waveform of interest. Output loaded with 50 pF.
28. Oscillator start-up time varies with crystal parameters. This specification does not apply when using an
external clock source.
