CD74HCT257E Overview


In order to conserve board space, digital switch is included in the 16-DIP (0.300, 7.62mm).It is packaged according to the Tube method.The method digital switch ic adopts for mounting is Through Hole.The analog IC in the multiplexers is identified as Multiplexer.By maintaining the operating temperature at -55°C~125°C, turn signal switch will not be affected by external factors.When operated with a 4.5V~5.5V supply voltage, digital controlled switch provides digital controlled switch's superior flexibility for designers.The multiplexers can be used for a wide range of applications since they are members of 74HCT series.There are 16 terminations included in its basic configuration.The multiplexer's system works with 5V voltage.In the HCT family, the logic switch is included.To avoid unnecessary failures, keep the supply voltage at 4.5V (Vsup).It is advisable to keep the maximum supply voltage (Vsup) at 5.5V so as to avoid some unnecessary failures.For the turn signal switch's operation, there are 1 outputs.This multiplexer has 2 inputs.
