SN74HC257PWRG4 Overview


Due to the fact that it is provided in the 16-TSSOP (0.173, 4.40mm Width), digital switch allows the board to be compacted.The package is packaged in the manner of Tape & Reel (TR).Surface Mount is the mounting method digital switch ic uses.In the multiplexers, the analog IC Multiplexer is used.As long as the operating temperature is -40°C~85°C, turn signal switch will not be influenced by external factors.It provides digital controlled switch's superior flexibility for designers to use when it operates with a supply voltage of 2V~6V.provides digital controlled switch's digital controlled switch'sMultiplexers of the 74HC series can be used in a wide range of applications.Among its basic configurations are 16 terminations.The part number for 74HC257 can be used to find its logic switch related parts as well.For multiplexer's system, 5V voltage is supplied.This turn signal switch consists of 16 component pins.Conductors terminate at GULL WING in this design.The supply type of this multiplexer ic is Single.This multiplexer ic has 16 pins configured.The multiplexer ic is mounted in the direction of Surface Mount.In the HC/UH family, the logic switch is included.In the signal multiplexer, there are 2 bits available.Vsup should be kept at 2V to prevent some unnecessary failures.In order to avoid some unnecessary failures, you should maintain a maximum supply voltage (Vsup) of 6V.The turn signal switch has 1 outputs.If the supply voltage is 5V, reliable performance of the multiplexers can be achieved.The multiplexer is equipped with 8 inputs.A TR packaging method is used in the switches.The turn signal switch's circuit consists of 4 channels that are being used for transmission in the circuit.
