74HC257N,652 Overview


It is included in the 16-DIP (0.300, 7.62mm) in order to save board space.Tube represents its packaging.Digital switch ic adheres to a mounting method of Through Hole.In the multiplexers, the analog IC is indicated by Multiplexer.When the operating temperature is kept at -40°C~125°C, the machine will not be sensturn signal switchive to external influences.Designers have greater flexibility using digital controlled switch when it works with 2V~6V voltage.With the 74HC series, the multiplexers are suitable for a diverse range of applications.There is a design for terminating 16 as part of its basic configuration.As its base part number is 74HC257, logic switch can also be used to find its related parts.The turn signal switch is supplied with a voltage of 5V volts.This turn signal switch contains 16 component pins.The logic switch is a member of the HC/UH family.Vsup should be kept at 2V to prevent some unnecessary failures.Avoid unnecessary failures by keeping Vsup at 6V.The power supply of 2/6V is provided for mux switch's normal operation.The turn signal switch has 1 outputs designed for operation.It has 2 inputs.
