DM74ALS257N Overview
Digital switch is provided in the 16-DIP (0.300, 7.62mm) for the purpose of saving board space.As a result, it is packaged in a way that is referred to as Tube.digital switch ic uses the method of Through Hole for mounting.In the multiplexers, the analog IC Multiplexer is used.As long as the operating temperature is 0°C~70°C, turn signal switch will not be influenced by external factors.It provides digital controlled switch's superior flexibility for designers to use when it operates with a supply voltage of 4.5V~5.5V.provides digital controlled switch's digital controlled switch'sMultiplexers of the 74ALS series can be used in a wide range of applications.There is a base part number 74ALS257 that can be used to locate signal switch's related components as well.There is a type of supply of Single.The board is configured with 16 pins.As you can see, it is mounted in the direction of Through Hole.In the signal multiplexer, there are 4 bits available.Without any external influences, it consumes 9mA current of multiplexer ic at all times.Using a supply voltage of 5V can result in reliable performance of the multiplexers.This multiplexer has 8 inputs.There are 2 output lines on the signal source.
