SN74HCT257N Overview


The reason it is provided is that the board space can be saved by placing digital switch in the 16-DIP (0.300, 7.62mm).The package is in the form of Tube.In terms of mounting, digital switch ic uses the Through Hole method .The analog IC in the multiplexers is identified as Multiplexer.By keeping the operating temperature at -40°C~85°C, turn signal switch will not be affected by external factors.With a supply voltage of 4.5V~5.5V, designers have greater flexibility of digital controlled switch.These multiplexers are members of the 74HCT series, which provide extensive application potential.There is a design for terminating 16 as part of its basic configuration.You can also find related parts by using its logic switch base part number of 74HCT257.The multiplexer's system is supplied with a voltage of 5V.This turn signal switch has 16 component pins.This supply type employs Single.With 16 pins, it is configured.The multiplexer ic is mounted in the direction of Through Hole.I would like to refer to the logic switch as a member of the HCT family.There are 2 bits in signal multiplexer.There is a power supply provided for the mux switch's normal operation of 5V.This turn signal switch has 1 outputs designed for its operation.With a supply voltage of 5V, reliable performance of the multiplexers can be achieved.In this multiplexer, there is a total of 8 inputs.This turn signal switch's circuit is based on a circuit with 4 channels.
