74F521SJ Overview
Packages are made from materials supplied by Tube.There is no doubt that the 20-SOIC (0.209, 5.30mm Width) is well known in the electronic industry due to its low package cost.Electronic parts using 8 Bits are designed here.74F Series offers outstanding performance-cost ratios.Mounted in the middle of Surface Mount is this electronic part.This electrical device produces Active Low as its output.4.5V~5.5V Supply Voltage provides the device with the necessary stability.In order to ensure its reliability, it operates at a temperature of 0°C~70°C.Applications for the Identity Comparator Type are standard grade.As the output current of 1mA 20mA is high/low, it has maximum design flexibility.Programming terminations is done using 20.With 1 Functions, it can perform a variety of tasks.The device is powered by a voltage of 5V.The 20 Pin Count feature is included.Electronic devices of this type are known as F/FAST devices.At 5.5V, the supply voltage reaches its maximum value (Vsup).Comparator is recommended that the supply voltage (Vsup) be greater than 4.5V.In addition to CASCADABLE, for example, other additions have been made.
