74F521SC Overview
Packaging is made from materials provided by Tube.Known for its low package costs, the 20-SOIC (0.295, 7.50mm Width) is a popular electronic component.An electronic part designed with 8 Bits is used in this product.74F Series' performance-to-cost ratio is excellent.There is a Surface Mount-position for this electronic part.The electrical device has an output of Active Low.To ensure proper functioning, a 4.5V~5.5V Supply Voltage is provided.Comparator operates wComparatorh the Operating Temperature of 0°C~70°C to ensure Comparators reliabilComparatory.For standard grade applications, the Identity Comparator Type is suitable.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.Supply Voltage 5V powers the device.In addition, it features 20 Pin Count.F/FAST is the family name of this electronic device.A maximum voltage supply (Vsup) is reached at 5.5V.Comparator is important that the Supply Voltage (Vsup) is greater than 4.5V.There are a few additions, such as CASCADABLE.
