MC74VHC257DR2 Overview
Due to the lack of space on the board, digital switch is provided in the 16-SOIC (0.154, 3.90mm Width).Tape & Reel (TR) is the packaging method.As far as mounting is concerned, digital switch ic uses Surface Mount.In the multiplexers, the analog IC Multiplexer is used.The operating temperature of -55°C~125°C will not be susceptible to external factors.With a supply voltage of 2V~5.5V, designers have greater flexibility of digital controlled switch.These multiplexers are members of the 74VHC series, which provide extensive application potential.As part of its basic configuration, 16 terminations are designed as a part of it.You can also find related parts by using its logic switch base part number of 74VHC257.The multiplexer's system is powered by 3.3V voltage.This turn signal switch has 16 component pins.At the end of a conductor, it uses GULL WING as the point where the conductor ends.There is a supply type of Single employed as part of this supply.It is configured with 16 pins.The mounting point is Surface Mount.In the AHC/VHC family, the logic switch is included.In order to prevent unnecessary failures, it is recommended that the minimal supply voltage (Vsup) be kept at 2V.In order to avoid unnecessary failures, the maximum supply voltage (Vsup) should be kept at 5.5V.A power supply is provided for mux switch's normal operation of 2/5.5V.The turn signal switch has 1 outputs designed for operation.Currently, the switches is packaged in accordance with the TAPE AND REEL method.It is possible to accept voltage levels through 8 input lines of multiplexers.To ensure that the digitalswitch performs properly, 4 circuits are formed.
