SN74HC251NSR Overview
It is included in the 16-SOIC (0.209, 5.30mm Width) in order to save board space.The package is packaged in the manner of Cut Tape (CT).In terms of mounting, digital switch ic uses the Surface Mount method .The analog IC in the multiplexers is identified as Multiplexer.When the operating temperature is kept at -40°C~85°C, the machine will not be sensturn signal switchive to external influences.With a supply voltage of 2V~6V, designers have greater flexibility of digital controlled switch.Multiplexers in the 74HC series are suitable for a wide range of applications.This configuration includes 16 terminations as part of its basic functionality.In addition, it also has a base part number of 74HC251, which can be used to find related parts.The multiplexer is supplied with 5V voltage.This turn signal switch contains 16 component pins.Conductors terminate at GULL WING in this design.Single is used as its supply type.With 16 pins, it is configured.As you can see, it is mounted in the direction of Surface Mount.I would like to refer to the logic switch as a member of the HC/UH family.As a result, signal multiplexer provides a total of 8 bits.Avoid unnecessary failures by keeping the supply voltage (Vsup) at 2V.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.The turn signal switch operates with 1 outputs.When a supply voltage of 5V is used, reliable performance of the multiplexers can be achieved.This multiplexer is equipped with 8 inputs and 8 outputs.In accordance with TR, switches can be packaged.A normal operation of the digitalswitch requires 1 circuits.
