MC74VHC257DTG Overview
This is a relatively small item of digital switch that is included in the 16-TSSOP (0.173, 4.40mm Width) in order to save space on the board.Tube represents its packaging.In terms of mounting, digital switch ic uses the method of Surface Mount.The analog IC in the multiplexers is identified as Multiplexer.A temperature of -55°C~125°C will not leave the turn signal swturn signal switchch susceptible to external influences.The turn signal switch is designed for use with a 2V~5.5V supply voltage, which gives it a lot of flexibility.Multiplexers from the 74VHC series can be used in a wide range of applications.As parts of its basic configuration, 16 terminations are desgined.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 has a total of 16 component pins.Conductors terminate at GULL WING in this design.Its supply type is Single, which is used as the source of power.With 16 pins, it is configured.Surface Mount is the way it is mounted.There is a family of AHC/VHC members.It is recommended that the minimum supply voltage (Vsup) be kept at 2V to avoid some unnecessary failures.In order to avoid some unnecessary failures, you should maintain a maximum supply voltage (Vsup) of 5.5V.For mux switch's normal operation, there is a power supply provided at 2/5.5V.RAIL is used to package the switches.Voltage levels are accepted through 8 input lines of multiplexers.As the signal source, there are 4 output lines.
