SN74ALS521N Overview


Tube's materials are used for the packaging.Low package costs are a common attribute of the 20-DIP (0.300, 7.62mm) in the electronic industry.The electronic part in this photo is designed using 8 Bits.Its performance-cost ratio makes the 74ALS Series an excellent value.Mounted in the way of Through Hole, this electronic part is mounted in the way of X.Using this electrical device, Active Low is the output.There is a 4.5V~5.5V Supply Voltage present in order to ensure normal device operation.For reliability, it uses the Operating Temperature 0°C~70°C.Applications for the Identity Comparator Type are standard grade.As 2.6mA 24mA features a high/low output current, maximal design flexibility can be achieved.The 20 termination method ends a transmission line with a device that matches the line's characteristic impedance.The device is equipped with 1 functions.Comparator can be established which parts are related to a Base Part Number.Supply Voltage 5V powers the device.Count of 20 pins is provided.There are 20 pins, which are pronged contacts as part of a signal interface in a computer or other communications device. This electronic part is mounted in the way of Through Hole.ALS is the family name of this electronic device.You can find it under Arithmetic Circuits Subcategory.Comparator operates from a 5V Power Supplies.In addition to WITH PULL-UP RESISTORS ON Q INPUTS; CASCADABLE, for example, other additions have been made.The Supply Voltage should be maintained at 5V.Comparator reaches 19mA when Comparator is supplied wComparatorh the highest possible power current (ICC).As it is able to operate with a supply voltage of 12mA, it is a highly versatile device.
