74HCT257N,652 Overview
In order to save board space, digital switch is located in the 16-DIP (0.300, 7.62mm).The package is packaged in the manner of Tube.digital switch ic uses the method of Through Hole for mounting.the multiplexers uses an analog IC Multiplexer.As long as the operating temperature is -40°C~125°C, turn signal switch will not be influenced by external factors.Designers have greater flexibility using digital controlled switch when it works with 4.5V~5.5V voltage.The multiplexers can be used for a wide range of applications since they are members of 74HCT series.It is designed with 16 terminations as part of its basic configuration.Its logic switch base part number is 74HCT257 which can also be used to find its logic switch related parts.The multiplexer's system is powered by 5V volts.Currently, this turn signal switch has a total of 16 component pins.The logic switch is a member of the HCT family.The minimal supply voltage (Vsup) should be kept at 4.5V to avoid some unnecessary failures.To avoid some unnecessary failures, the maximum supply voltage (Vsup) should be kept at 5.5V.It is provided that 5V has a power supply in order to function normally.The turn signal switch has 1 outputs.This multiplexer has 2 inputs.
