SN74LS157DR Overview
Digital switch is provided in the 16-SOIC (0.154, 3.90mm Width) for the purpose of saving board space.As a result, it is packaged in the way of Cut Tape (CT).The method digital switch ic adopts for mounting is Surface Mount.The multiplexers uses an analog IC Multiplexer as the analog part of the circuit.By keeping the operating temperature at 0°C~70°C, turn signal switch will not be affected by external factors.With a supply voltage of 4.75V~5.25V, designers have greater flexibility of digital controlled switch.The multiplexers from 74LS series can be used for a wide range of applications.There is a design for terminating 16 as part of its basic configuration.The base part number is 74LS157, which can also be used to find its logic switch related parts.The multiplexer's system is supplied with a voltage of 5V.This turn signal switch consists of 16 component pins.Using the point GULL WING as an end point of conductors, it is used to determine the terminus of a conductor.Single is employed as its supply type.It is configured with 16 pins.Surface Mount is the way it is mounted.In the LS family, the logic switch is included.There are 4 bits signal multiplexer provides.mux switch's normal operation requires the power supply of 5V.The turn signal switch operates with 1 outputs.In the absence of external influences, 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.TR is used to package the switches.The multiplexers have2 input lines on the board that accept voltage levels.It is necessary for the digitalswitch to operate normally that 4 circuits be formed.
