SN74ALS857NT Overview
This is a relatively small item of digital switch that is included in the 24-DIP (0.300, 7.62mm) in order to save space on the board.Tube is the method used for packaging.The mounting method digital switch ic uses is Through Hole.The analog IC used in the multiplexers can be referred to as Multiplexer.By keeping the operating temperature at 0°C~70°C, turn signal switch will not be affected by external factors.When digital controlled switch operates at 4.5V~5.5V, designers have superior flexibility.Several applications are possible for 74ALS series multiplexers.Among its basic configurations are 24 terminations.The base part number is 74ALS857, so you can find its logic switch related parts using that number.In multiplexer's system, 5V is the voltage supplied.This turn signal switch has a total of 24 component pins.As a type of supply, Single is employed.The board is configured with 24 pins.The mounting is in the way of Through Hole.The logic switch belongs to the family of ALS.For mux switch's normal operation, power supply 5V is provided.In order for the turn signal switch to work, there are 6 outputs.The performance of the multiplexers of a system can be reliably achieved with a supply voltage of 5V.There are 12 inputs provided in this multiplexer.As a voltage level input, the multiplexers have 2 lines.
