M74HC251B1R Overview


In order to save board space, digital switch is located in the 16-DIP (0.300, 7.62mm).It is packaged according to the Tube method.The mounting method digital switch ic uses is Through Hole.the multiplexers uses IC Multiplexer as the analog IC.The operating temperature will not be affected by external factors when turn signal switch is set to -55°C~125°C.Design engineers have more flexibility when digital controlled switch operates at 2V~6V voltage.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.The base part number is M74HC251, so you can find its logic switch related parts using that number.In this case, 4.5V is the voltage supplied to the multiplexer's system.Signal switch has 16 component pins.In this case, the supply type is Single.Currently, it is configured with 16 pins.Through Hole is the way it is mounted.The HC/UH family includes the logic switch.Vsup should be kept at 2V to prevent some unnecessary failures.It is advisable that the maximal supply voltage (Vsup) remains at 6V to avoid some unnecessary failures.This multiplexer provides 8 inputs.On the multiplexers, 3 input lines are provided for accepting voltage levels.In this case, the signal source has a total of 2 output lines.For the normal operation of the device, 1 circuits must be formed.
