CD74HCT257M Overview
Digital switch is provided in the 16-SOIC (0.154, 3.90mm Width) for the purpose of saving board space.The package is packaged in accordance with Tube.The mounting method digital switch ic uses is Surface Mount.For the analog part of the multiplexers, an IC Multiplexer is used.A temperature of -55°C~125°C will not leave the turn signal swturn signal switchch susceptible to external influences.Designers have greater flexibility when digital controlled switch operates at a 4.5V~5.5V supply voltage.Multiplexers in the 74HCT series are suitable for a wide range of applications.The basic configuration includes 16 terminations.The multiplexer's system is powered by 5V voltage.It employs GULL WING as the point at which conductors come to an end.I would like to refer to the logic switch as a member of the HCT family.Keep Vsup at 4.5V to avoid unnecessary failures.Keeping Vsup at 5.5V will prevent some unnecessary failures.As a result, the turn signal switch consists of 1 outputs.In this multiplexer, there is a total of 2 inputs.
