MC74VHC257DT Overview
In order to save board space, digital switch is located in the 16-TSSOP (0.173, 4.40mm Width).It is packaged according to the Tube method.Mounting is performed using Surface Mount.In the multiplexers, the analog IC is indicated by Multiplexer.Turn signal switch will not be susceptible to the external factors when the operating temperature is kept at -55°C~125°C.Using a 2V~5.5V supply voltage provides digital controlled switch's superior flexibility for designers.As a member of 74VHC series, the multiplexers can be used for a wide range of applications.Among its basic configurations are 16 terminations.There is a base part number of 74VHC257 which can also be used in order to locate the logic switch that are related to this item.The multiplexer's system is supplied with a voltage of 3.3V.This turn signal switch consists of 16 component pins.At the end of a conductor, it uses GULL WING as the point where the conductor ends.Its supply type is Single, which is used as the source of power.This multiplexer ic has 16 pins configured.Surface Mount is the way it is mounted.I would like to refer to the logic switch as a member of the AHC/VHC family.To avoid unnecessary failures, keep the supply voltage at 2V (Vsup).Vsup (maximum supply voltage) should be kept as 5.5V to prevent unnecessary failures.During mux switch's normal operation, 2/5.5V is provided with a power supply.The switches packaging is based on RAIL.In order to accept voltage levels, the multiplexers have input lines 8 on the board.There are 4 output lines designed to serve as the source of the signal.
