SN74LVC257AQDRG4Q1 Overview


As a means of saving space, digital switch is provided in the 16-SOIC (0.154, 3.90mm Width).The package is packaged in the manner of Tape & Reel (TR).The method digital switch ic adopts for mounting is Surface Mount.Multiplexer is the analog IC that the multiplexers uses.By keeping the operating temperature at -40°C~125°C, turn signal switch will not be affected by external factors.Designers have greater flexibility when digital controlled switch operates at a 2V~3.6V supply voltage.In addition to being a member of the Automotive, AEC-Q100, 74LVC series, these multiplexers have a wide range of applications.Among its basic features are 16 terminations.There is a base part number 74LVC257 that can be used to locate signal switch's related components as well.In multiplexer's system, 2.7V is the voltage supplied.This turn signal switch consists of 16 component pins.Conductors terminate at GULL WING in this design.Single is used as its supply type.The board is configured with 16 pins.This unit is mounted in the way of Surface Mount.I would like to refer to the logic switch as a member of the LVC/LCX/Z family.Signal multiplexer contains 2 bits.To avoid unnecessary failures, keep the supply voltage at 2V (Vsup).To avoid some unnecessary failures, the maximum supply voltage (Vsup) should be kept at 3.6V.The power supply of 3.3V is provided for mux switch's normal operation.There are 1 outputs designed to operate the turn signal switch.It has 8 inputs.A TR packaging method is used in the switches.This turn signal switch's circuit uses 4 transmission channels.
