SN74LS157D Overview
It is included in the 16-SOIC (0.154, 3.90mm Width) in order to save board space.The package is in the form of Tube.Digital switch ic adheres to a mounting method of Surface Mount.For the analog part of the multiplexers, an 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.Designers have greater flexibility using digital controlled switch when it works with 4.75V~5.25V voltage.Several applications are possible for 74LS series multiplexers.The basic configuration includes 16 terminations.The multiplexer's system works with 5V voltage.In this turn signal switch, there are 16 component pins.As the end of conductors, it uses GULL WING.The logic switch is included into the family of LS.In order to prevent unnecessary failures, it is recommended that the minimal supply voltage (Vsup) be kept at 4.75V.In order to avoid some unnecessary failures, you should maintain a maximum supply voltage (Vsup) of 5.25V.For the turn signal switch's operation, there are 1 outputs.A multiplexer such as this has 2 inputs available.
