The Form Fit Function (FFF) tab will give you the options that are more likely to serve as direct pin-to-pin alternates or drop-in parts. The Functional Equivalents tab will give you options that are likely to match the same function of SA556N, but it may not fit your design. Always verify details of parts you are evaluating, as these parts are offered as suggestions for what you are looking for and are not guaranteed.
SA556N Frequently Asked Questions (FAQ)
-
The recommended operating voltage range for SA556N is 4.5V to 16V, although it can operate up to 18V with reduced performance.
-
To ensure the oscillator starts reliably, make sure to decouple the VCC pin with a 10nF to 100nF capacitor, and use a high-quality quartz crystal with a load capacitance of 18pF to 22pF.
-
The maximum frequency deviation of the SA556N oscillator is ±100ppm over the entire operating temperature range of -40°C to 125°C.
-
No, the SA556N is designed to work with an external quartz crystal and cannot be used in a crystal-less oscillator configuration.
-
The ESR of the crystal can be calculated using the formula: ESR = (Rs + Rp) / Q, where Rs is the series resistance, Rp is the parallel resistance, and Q is the quality factor of the crystal.
