C to + C Storage Temperature Range...- C to +12 C Soldering Temperature...See IPC/JEDEC J-STD-020 Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. RECOMMENDED OPERATING CONDITIONS (T A = C to + C) Supply Voltage (Note 1) 2..

This is the change in output frequency due to changes in voltage at. This is the change in output frequency due to changes in temperature from the +2 C frequency at =.V. Guaranteed by design. This indicates the time elapsed between power-up and the output becoming active. An on-chip delay is intentionally introduced to allow the oscillator to stabilize. t STAB is equivalent to approximately 12 clock cycles and will depend on the programmed oscillator frequency. Output disabled in 2 cycles or less of the output frequency. Output voltage swings may be impaired at high frequencies combined with high-output loading.

5 PIN NAME FUNCTION 1 Oscillator Output 2 Power Supply Power Supply Ground Ground Power-Down. When the pin is high, the oscillator is enabled. When the pin is low, the oscillator is disabled (power-down mode). Do Not Connect. The pins are internally connected to ground.
