74F521SJX Overview
Packages are made from materials supplied by Tape & Reel (TR).Known for its low package costs, the 20-SOIC (0.209, 5.30mm Width) is a popular electronic component.Comparator is designed with 8 Bits.74F Series' performance-to-cost ratio is excellent.There is a Surface Mount-position for this electronic part.The output of this electrical device is Active Low. Providing a 4.5V~5.5V Supply Voltage ensures that the device operates normally.Ensure its reliability by operating at 0°C~70°C Operating Temperature.Comparator is suComparatorable for standard grade applications.As the output current of 1mA 20mA is high/low, it has maximum design flexibility.An example of a 20 termination is the practice of terminating a transmission line using an impedance-matching device.The 1-functions are included.There is a supply voltage of 5V that powers it.With 20 Pin Count, it is equipped with the latest technology.F/FAST is the family name of this electronic device.In this case, Vsup reaches a maximum level.There should be more supply voltage (Vsup) than 4.5V.For instance, CASCADABLE was added.
