74AC257SCX Overview
Providing this information in the 16-SOIC (0.154, 3.90mm Width) enables digital switch board space to be saved.It is packaged according to the Tape & Reel (TR) method.In terms of mounting, digital switch ic uses the method of Surface Mount.In the multiplexers, the analog IC Multiplexer is used.The operating temperature will not be affected by external factors when turn signal switch is set to -40°C~85°C.With a supply voltage of 2V~6V, designers have greater flexibility of digital controlled switch.Multiplexers in the 74AC series are suitable for a wide range of applications.As part of its basic configuration, 16 terminations are designed as a part of it.Currently, this turn signal switch has a total of 16 component pins.Conductors terminate at GULL WING in this design.The logic switch belongs to the family of AC.Keeping Vsup at 2V will prevent some unwanted failures.It is advisable to keep the maximum supply voltage (Vsup) at 6V so as to avoid some unnecessary failures.There are 1 outputs designed for the operation of the turn signal switch.This multiplexer has 2 inputs.
