SN74ALS521NSR Overview

Material from Cut Tape (CT) is used in the packaging.Low package costs are a common attribute of the 20-SOIC (0.209, 5.30mm Width) in the electronic industry.Using 8 Bits, this electronic component was designed.74ALS Series' performance-to-cost ratio is excellent.Surface Mount is used for mounting this electronic part.An electrical device of this type produces Active Low as an output.Devices need a 4.5V~5.5V Supply Voltage to function normally.In order to ensure its reliability, it operates at a temperature of 0°C~70°C.Identity Comparator Types can be used for standard-grade applications.The High/Low output current of 2.6mA 24mA makes it capable of securing maximum design flexibility.The 20 command is used to program terminations.The device has 1 functions.Based on the Base Part Number, related parts can be identified.Power is provided by a supply voltage of 5V.20 Pin Count is built into it.In a computer or other communications device, there are 20 pins, which are pronged contacts.Mounting of this electronic component is in the direction of Surface Mount.ALS family electronic devices belong to this category.Arithmetic Circuits is a Subcategory.Power is supplied by a 5V Power Supply.As an example, WITH PULL-UP RESISTORS ON Q INPUTS; CASCADABLE is among the additions.Comparator is necessary to maintain a 5V supply voltage.In TR, it provides reliable performance.ICC reaches 19mA when the maximum power is supplied for its operation.With its high output current, 24mA offers maximum design flexibility.
