MC74VHC257MEL Overview
Providing this information in the 16-SOIC (0.209, 5.30mm Width) enables digital switch board space to be saved.Tape & Reel (TR) represents its packaging.Digital switch ic adheres to a mounting method of Surface Mount.For the analog part of the multiplexers, an IC Multiplexer is used.If the operating temperature is maintained at -55°C~125°C, turn signal switch will not be susceptible to external factors.With a supply voltage of 2V~5.5V, designers have greater flexibility of digital controlled switch.In addition to being a member of the 74VHC series, these multiplexers have a wide range of applications.It is designed with 16 terminations as part of its basic configuration.Its logic switch base part number is 74VHC257 which can also be used to find its logic switch related parts.The turn signal switch is supplied with a voltage of 3.3V volts.In this turn signal switch, there are 16 component pins.As a result, conductors end at GULL WING.As a type of supply, Single is employed.This unit is mounted in the way of Surface Mount.There is a family of AHC/VHC members.Avoid unnecessary failures by keeping the supply voltage (Vsup) at 2V.It is advisable to keep the maximum supply voltage (Vsup) at 5.5V so as to avoid some unnecessary failures.For mux switch's normal operation, there is a power supply provided at 2/5.5V.In this multiplexer, there is a total of 2 inputs.The switches package is packaged in accordance with the TAPE AND REEL method.For the purpose of accepting voltage levels, the multiplexers have 8 input lines.Signal sources consist of output lines of 4.
