CD74HC251E Overview


For the purpose of saving board space, digital switch is included in the 16-DIP (0.300, 7.62mm).In this case, it is packaged as Tube.The method digital switch ic adopts for mounting is Through Hole.The multiplexers uses an analog IC Multiplexer as the analog part of the circuit.Turn signal switch will not be susceptible to the external factors when the operating temperature is kept at -55°C~125°C.Design engineers have more flexibility when digital controlled switch operates at 2V~6V voltage.These multiplexers are members of the 74HC series, which provide extensive application potential.This configuration includes 16 terminations as part of its basic functionality.Its logic switch base part number is 74HC251 which can also be used to find its logic switch related parts.In this case, 4.5V is the voltage supplied to the multiplexer's system.In this turn signal switch, there are 16 component pins.There is a type of supply Single that is employed in this case.With 16 pins, it is configured.It is mounted in the way of Through Hole.Among the family of HC/UH the logic switch is a member.The multiplexer ic provides 2 bits.Avoid unnecessary failures by keeping the supply voltage (Vsup) at 2V.In order to avoid some unnecessary failures, you should maintain a maximum supply voltage (Vsup) of 6V.As part of the operation of this turn signal switch, there are 1 outputs.The multiplexer provides 8 inputs.
