DM74ALS521N Overview
Tube's packaging is made of Tube's materials.Electronic manufacturers are well aware of the 20-DIP (0.300, 7.62mm) because of its low package cost.8 Bits were used to design this electronic part.With its excellent performance-cost ratio, the 74ALS Series is a great value.There is a Through Hole-position for this electronic part.Using this electrical device, Active Low is the output.An internal 4.5V~5.5V Supply Voltage ensures the device's normal operation.Ensure its reliability by operating at 0°C~70°C Operating Temperature.Identity Comparator Types are suitable for use in standard grade applications.As a result of the high/low output current feature, 2.6mA 24mA offers maximum design flexibility.An example of a 20 termination would be one in which the characteristic impedance of the transmission line is matched to the device terminating the transmission line.The device has 1 functions.The device is powered by a voltage of 5V.Count of 20 pins is provided.ALS devices are electronic devices.The maximal Supply Voltage (Vsup) reaches 5.5V.There should be more supply voltage (Vsup) than 4.5V.
