SN74ALS521DWRE4 Product Details

SN74ALS521DWRE4 Overview


Tape & Reel (TR)'s materials went into the packaging.Electronic manufacturers are well aware of the 20-SOIC (0.295, 7.50mm Width) because of its low package cost.A 8 Bit electronic part is used to design this part.74ALS Series provides excellent value for its performance-cost ratio.Electronic part Surface Mount is mounted here.An electrical device of this type produces Active Low as an output.Providing 4.5V~5.5V Supply Voltage is necessary to ensure the device's normal functioning.Ensure its reliability by operating at 0°C~70°C Operating Temperature.Application grade Identity Comparator Types are available.As a result of the high/low output current feature, 2.6mA 24mA offers maximum design flexibility.Comparator is possible to program terminations wComparatorh 20.1 functions are available on it.The related parts can be found based on the Base Part Number.There is a supply voltage of 5V that powers it.The device is equipped with a 20 Pin Count.The pronged contacts on computers and other communications devices are called 20 pins.A Surface Mount-shaped electronic part is mounted here.ALS family electronic devices belong to this category.Comparator can be found under the Arithmetic Circuit Subcategory.Power is supplied by a 5V Power Supply.There are a few additions, such as WITH PULL-UP RESISTORS ON Q INPUTS; CASCADABLE.Maintain a voltage of 5V for the supply voltage.Despite TR, the device's reliability makes it a good choice.This device's maximum power output (ICC) is determined by 19mA.
