SN74HC251DG4 Product Details

SN74HC251DG4 Overview


Digital switch is provided in the 16-SOIC (0.154, 3.90mm Width) for the purpose of saving board space.Tube represents its packaging.digital switch ic uses the method of Surface Mount for mounting.For the analog part of the multiplexers, an IC Multiplexer is used.By keeping the operating temperature at -40°C~85°C, turn signal switch will not be affected by external factors.Using a 2V~6V supply voltage provides digital controlled switch's superior flexibility for designers.These multiplexers are members of the 74HC series, which provide extensive application potential.As part of its basic configuration, 16 terminations are designed as a part of it.As its base part number is 74HC251, logic switch can also be used to find its related parts.In multiplexer's system, 5V is the voltage supplied.In this turn signal switch, there are 16 component pins.GULL WING is used as the point at which the conductors come to an end as part of this formula.There is a type of supply of Single.The board has 16 pins configured.Multiplexer ics are mounted in the direction of Surface Mount.The logic switch is a member of the HC/UH family.Signal multiplexer consists of 8 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.A power supply is provided for mux switch's normal operation of 2/6V.In order for the turn signal switch to work, there are 1 outputs.The performance of the multiplexers of a system can be reliably achieved with a supply voltage of 5V.The multiplexer is equipped with 8 inputs.
