CD74HC257E Overview


Due to the fact that it is provided in the 16-DIP (0.300, 7.62mm), digital switch allows the board to be compacted.Tube is the packaging method.Mounting is performed using Through Hole.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.It provides digital controlled switch's superior flexibility for designers to use when it operates with a supply voltage of 2V~6V.provides digital controlled switch's digital controlled switch'sMultiplexers from the 74HC series can be used in a wide range of applications.As parts of its basic configuration, 16 terminations are desgined.The base part number is 74HC257, which can also be used to find its logic switch related parts.The multiplexer's system is supplied with a voltage of 4.5V.Currently, this turn signal switch has a total of 16 component pins.In this case, Single is employed as the supply type.With 16 pins, it is configured.The mount is in Through Hole.In the HC/UH family, the logic switch is included.Signal multiplexer consists of 2 bits.The minimal supply voltage (Vsup) should be kept at 2V to avoid some unnecessary failures.In order to avoid unnecessary failures, the maximum supply voltage (Vsup) should be kept at 6V.The turn signal switch has 1 outputs.This multiplexer is equipped with 8 inputs and 8 outputs.The turn signal switch's circuit has 4 transmission channels.
