SN74LS157D Overview
This is a relatively small item of digital switch that is included in the 16-SOIC (0.154, 3.90mm Width) in order to save space on the board.As a result, it is packaged in a way that is referred to as Tube.Digital switch ic adheres to a mounting method of Surface Mount.As the analog part, the circuit uses an analog IC Multiplexer.By keeping the operating temperature at 0°C~70°C, turn signal switch will not be affected by external factors.When operated with a 4.75V~5.25V supply voltage, digital controlled switch provides digital controlled switch's superior flexibility for designers.Multiplexers of the 74LS series can be used in a wide range of applications.This configuration includes 16 terminations as part of its basic functionality.To find signal switch's related components, a base part number of 74LS157 may also be used.The multiplexer's system works with 5V voltage.In this turn signal switch, there are 16 component pins.GULL WING represents the end of conductors.There is a supply type of Single employed as part of this supply.Currently, it is configured with a 16 pin configuration.It is positioned in the direction of Surface Mount.The logic switch is a member of the family of LS.As a result, signal multiplexer provides 4 bits.During mux switch's normal operation, 5V is provided with a power supply.The turn signal switch has 1 outputs designed for operation.Without the influence of external factors, it consumes 9.7mA current of multiplexer ic.It is possible to achieve reliable performance of the multiplexers with a voltage supply of 5V.The multiplexer provides 8 inputs.Voltage levels are accepted through 2 input lines of multiplexers.The digitalswitch relies on 4 circuits to function normally.
