M74HC257B1R Overview


In order to save board space, digital switch is located in the 16-DIP (0.300, 7.62mm).As a result, it is packaged in the way of Tube.Digital switch ic uses a Through Hole mounting method.In the multiplexers, the analog IC is indicated by Multiplexer.The operating temperature will not be affected by external factors when turn signal switch is set to -55°C~125°C.The turn signal switch is designed for use with a 2V~6V supply voltage, which gives it a lot of flexibility.Since they are members of the 74HC series, they can be used in a wide variety of applications.As part of its basic configuration, 16 terminations are designed as a part of it.There is a base part number of M74HC257 which can also be used in order to locate the logic switch that are related to this item.The multiplexer's system works with 4.5V voltage.This turn signal switch consists of 16 component pins.The supply type of this multiplexer ic is Single.This multiplexer ic is configured with 16 pins.The mount is in Through Hole.There is a family of HC/UH members.Keep Vsup at 2V to avoid unnecessary failures.Vsup (maximum supply voltage) should be kept as 6V to prevent unnecessary failures.For mux switch's normal operation, there is a power supply provided at 2/6V.There are 1 outputs designed to operate the turn signal switch.This multiplexer is equipped with 8 inputs and 8 outputs.
