SN74ALS521DW Overview
Tube's packaging is made of Tube's materials.Low package costs are a common attribute of the 20-SOIC (0.295, 7.50mm Width) 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 middle of Surface Mount is this electronic part.The output of this electrical device is Active Low. Providing 4.5V~5.5V Supply Voltage is necessary to ensure the device's normal functioning.To ensure reliability, it operates at 0°C~70°C Operating Temperature.There is no minimum grade requirement for the Identity Comparator Type.The High/Low output current of 2.6mA 24mA makes it Feature maximum design flexibility.20 is used for terminating programs.There are 1 functions on it.Based on the Base Part Number, related parts can be identified.Supply Voltage 5V powers the device.20 Pin Count is built into it.The pronged contacts on computers and other communications devices are called 20 pins.Mounting of this electronic component is in the direction of Surface Mount.ALS devices are electronic devices.This can be found in Arithmetic Circuits's Subcategory.5V Power Supplies are used to power it.In addition to WITH PULL-UP RESISTORS ON Q INPUTS; CASCADABLE, for example, other additions have been made.5V should be maintained as the Supply Voltage.As the operation of the device is carried out, the maximum power current (ICC) supplied can reach a certain value.The output current of 24mA makes it Feature maximum design flexibility.
