DM74ALS157M Overview
In order to conserve board space, digital switch is included in the 16-SOIC (0.154, 3.90mm Width).In this case, it is packaged as Tube.The mounting method digital switch ic uses is Surface Mount.Multiplexer is the analog IC that the multiplexers uses.As long as the operating temperature is 0°C~70°C, turn signal switch will not be influenced by external factors.Designers have greater flexibility using digital controlled switch when it works with 4.5V~5.5V voltage.Several applications are possible for 74ALS series multiplexers.The base part number is 74ALS157, so you can find its logic switch related parts using that number.Its supply type is Single, which is used as the source of power.There are 16 pins on it.The multiplexer ic is mounted in the direction of Surface Mount.In this signal multiplexer, there are 4 bits that are provided.There are 4 outputs designed for the operation of the turn signal switch.If the supply voltage is 5V, reliable performance of the multiplexers can be achieved.There are 8 inputs provided in this multiplexer.It is possible to accept voltage levels by using one of the 1 input lines of multiplexers.A signal source is provided by 2 output lines.The maximum operating temperature of 70°C is acceptable for this signal switch.It is recommended that the minimal operating temperature of the multiplexer be maintained at 0°C.Upon compliance with the applicable device specifications, the device will operate at the maximum supply voltage of 5.5V.Device specifications require that the minimum supply voltage is 4.5V.
