CD74HC257M Product Details

CD74HC257M Overview


Due to the lack of space on the board, digital switch is provided in the 16-SOIC (0.154, 3.90mm Width).As a result, it is packaged in a way that is referred to as Tube.Surface Mount is the mounting method digital switch ic uses.the multiplexers uses IC Multiplexer as the analog IC.A temperature of -55°C~125°C will not leave the turn signal swturn signal switchch susceptible to external influences.A supply voltage of 2V~6V provides digital controlled switch's superior flexibility for designers.Several applications are possible for 74HC series multiplexers.As part of its basic configuration, 16 terminations are designed as a part of it.As its base part number is 74HC257, logic switch can also be used to find its related parts.The multiplexer's system is supplied with a voltage of 4.5V.This turn signal switch has 16 component pins.As a result, conductors end at GULL WING.Its supply type is Single, which is used as the source of power.The board is configured with 16 pins.The mount is in Surface Mount.The logic switch belongs to the family of HC/UH.As a result, signal multiplexer provides 2 bits.Avoid unnecessary failures by keeping the supply voltage (Vsup) at 2V.The maximal supply voltage (Vsup) should be kept at 6V to avoid some unnecessary failures.For the turn signal switch's operation, there are 1 outputs.This multiplexer is equipped with 8 inputs and 8 outputs.There are a total of 4 channels used for transmitting data in the turn signal switch's circuit.

CD74HC257M Features
