SN74ALS257AN Overview
Due to the lack of space on the board, digital switch is provided in the 16-DIP (0.300, 7.62mm).As a result, it is packaged in a way that is referred to as Tube.In terms of mounting, digital switch ic uses the method of 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.As part of its basic configuration, 16 terminations are designed as a part of it.The base part number is 74ALS257, which is also useful when looking up signal switch's related components.In this case, 5V is the voltage supplied to the multiplexer's system.This turn signal switch has a total of 16 component pins.In this case, the supply type is Single.A total of 16 pins are configured on this board.The mounting is in the way of Through Hole.In the ALS family, the logic switch is included.In this signal multiplexer, there are 2 bits provided.It is provided that 5V has a power supply in order to function normally.As part of the operation of this turn signal switch, there are 1 outputs.Without the influence of external factors, it consumes 9mA current of multiplexer ic.If the supply voltage is 5V, reliable performance of the multiplexers can be achieved.There are 8 inputs provided in this multiplexer.In the turn signal switch's circuit, there are 4 channels used for transmission.
