74AC257MTR Overview


This is a relatively small item of digital switch that is included in the 16-SOIC (0.154, 3.90mm Width) in order to save space on the board.As a result, it is packaged in the way of Tape & Reel (TR).digital switch ic uses the method of Surface Mount for mounting.The multiplexers uses an analog IC Multiplexer as the analog part of the circuit.When the operating temperature is kept at -55°C~125°C, turn signal switch will not be susceptible to external factors.Designers have greater flexibility when digital controlled switch operates at a 2V~6V supply voltage.The multiplexers can be used for a wide range of applications since they are members of 74AC series.There is a design for terminating 16 as part of its basic configuration.In addition, it also has a base part number of 74AC257, which can be used to find related parts.The multiplexer's system is supplied with a voltage of 3.3V.In this turn signal switch, there are 16 components that can be connected to each pin.At the end of a conductor, it uses GULL WING as the point where the conductor ends.In this case, the supply type is Single.A total of 16 pins are configured on this board.Surface Mount is the way it is mounted.The logic switch is a member of the AC family.It is recommended that the minimum supply voltage (Vsup) be kept at 2V to avoid some unnecessary failures.It is advisable to keep the maximum supply voltage (Vsup) at 6V so as to avoid some unnecessary failures.A power supply is provided for mux switch's normal operation of 3.3/5V.The turn signal switch operates with 1 outputs.The multiplexer is equipped with 8 inputs.TAPE AND REEL is used to package the switches.To ensure that the digitalswitch performs properly, 4 circuits are formed.
