Silicon Oscillator with Low-Power

Frequency Switching and Reset Output

_______________________________________________________________________________________

Note 1: All parameters are tested at TA = +25°C. Specifications over temperature are guaranteed by design.

Note 2: The frequency is determined by part number selection. See the Ordering Information.

Note 3: Guaranteed by design. Not production tested.

ELECTRICAL CHARACTERISTICS (continued)

(VCC = 2.7V to 5.5V, VL = VCC, TA = -40°C to +125

°C, unless otherwise noted. Typical values are at VCC = 5V, TA = +25°C.) (Note 1)
