CD74AC257M Overview
Due to the fact that it is provided in the 16-SOIC (0.154, 3.90mm Width), digital switch allows the board to be compacted.Tube is the method used for packaging.Digital switch ic adheres to a mounting method of Surface Mount.The analog IC used in the multiplexers can be referred to as Multiplexer.The operating temperature of -55°C~125°C will not be susceptible to external factors.With a supply voltage of 1.5V~5.5V, designers have greater flexibility of digital controlled switch.Multiplexers from the 74AC series can be used in a wide range of applications.The basic configuration includes 16 terminations.The multiplexer's system works with 5V voltage.It employs GULL WING as the point at which conductors come to an end.The logic switch belongs to the family of AC.It is advisable to keep the maximum supply voltage (Vsup) at 5.5V in order to prevent some unnecessary failures.There are 1 outputs designed to operate the turn signal switch.This multiplexer has 2 inputs.
