SN74LS253D Overview
For the purpose of saving board space, digital switch is included in the 16-SOIC (0.154, 3.90mm Width).Tube is the method used for packaging.Digital switch ic uses a Surface Mount mounting method.In the multiplexers, the analog IC Multiplexer is used.The operating temperature will not be affected by external factors when turn signal switch is set to 0°C~70°C.Using a 4.75V~5.25V supply voltage provides digital controlled switch's superior flexibility for designers.Several applications are possible for 74LS series multiplexers.Among its basic features are 16 terminations.The base part number is 74LS253, which can also be used to find its logic switch related parts.The multiplexer's system is powered by 5V volts.In this turn signal switch, there are 16 components that can be connected to each pin.Using the point GULL WING as an end point of conductors, it is used to determine the terminus of a conductor.The logic switch is a member of the LS family.Avoid unnecessary failures by keeping the supply voltage (Vsup) at 4.75V.Keeping Vsup at 5.25V will prevent some unnecessary failures.In order to maintain mux switch's normal operation, power is provided to 5V.The turn signal switch operates with 1 outputs.It is provided with 4 inputs.
