DM74ALS521WM Overview
Packaging made from Tube's materials.There is no doubt that the 20-SOIC (0.295, 7.50mm Width) is well known in the electronic industry due to its low package cost.Comparator is designed with 8 Bits.Its performance-cost ratio makes the 74ALS Series an excellent value.Mounted in the way of Surface Mount, this electronic part is mounted in the way of X.An electrical device of this type produces Active Low as an output.4.5V~5.5V Supply Voltage provides the device with the necessary stability.Comparator operates wComparatorh the Operating Temperature of 0°C~70°C to ensure Comparators reliabilComparatory.The Identity Comparator Type qualifies for standard grade applications.As a result of the high/low output current feature, 2.6mA 24mA offers maximum design flexibility.A 20 termination consists of terminating transmission lines with a device matching the line's characteristic impedance.The device is equipped with 1 functions.Power is provided by a supply voltage of 5V.20 Pin Count is equipped with it.ALS family electronic devices belong to this category.Vsup reaches its maximal value at 5.5V.Comparator is important that the Supply Voltage (Vsup) is greater than 4.5V.
