74AHC257D,112 Overview
Due to the lack of space on the board, digital switch is provided in the 16-SOIC (0.154, 3.90mm Width).Tube is the method used for packaging.In terms of mounting, digital switch ic uses the method of Surface Mount.The multiplexers uses an analog IC Multiplexer as the analog part of the circuit.In the case of -40°C~125°C, turn signal switch will not be affected by external factors.It provides digital controlled switch's superior flexibility for designers to use when it operates with a supply voltage of 2V~5.5V.provides digital controlled switch's digital controlled switch'sThese multiplexers are members of the 74AHC series, which provide extensive application potential.There are 16 terminations included in its basic configuration.To find signal switch's related components, a base part number of 74AHC257 may also be used.The voltage supplied for multiplexer's system is 5V.multiplexer's systemThis turn signal switch consists of 16 component pins.It is the end of conductors that is represented by GULL WING.In this case, the supply type is Single.There are 16 pins on it.Multiplexer ics are mounted in the direction of Surface Mount.The AHC/VHC/H/U/V family includes the logic switch.Keeping Vsup at 2V will prevent some unwanted failures.With a supply voltage of 5V, reliable performance of the multiplexers can be achieved.It is possible to accept voltage levels through 8 input lines of multiplexers.A signal source is provided by 4 output lines.
