MC74VHC257DG Overview
In order to save board space, digital switch is located in the 16-SOIC (0.154, 3.90mm Width).As a result, it is packaged in the way of Tube.Mounting is performed using Surface Mount.In the multiplexers, the analog IC Multiplexer is used.Turn signal switch will not be susceptible to the external factors when the operating temperature is kept at -55°C~125°C.A supply voltage of 2V~5.5V provides digital controlled switch's superior flexibility for designers.Several applications are possible for 74VHC series multiplexers.The basic configuration of this system includes 16 terminations.There is a base part number 74VHC257 that can be used to locate signal switch's related components as well.In this case, 3.3V is the voltage supplied to the multiplexer's system.This turn signal switch contains 16 component pins.Using the point GULL WING as an end point of conductors, it is used to determine the terminus of a conductor.In this case, the supply type is Single.The board is configured with 16 pins.Multiplexer ics are mounted in the direction of Surface Mount.The logic switch is a member of the AHC/VHC family.Vsup should be kept at 2V to prevent some unnecessary failures.To avoid unnecessary failures, the maximum supply voltage (Vsup) should be kept at 5.5V.During mux switch's normal operation, 2/5.5V is provided with a power supply.Currently, the switches is packaged in accordance with the RAIL method.For the purpose of accepting voltage levels, the multiplexers have 8 input lines.As a signal source, there are 4 output lines.
