74F257ASJ Overview
The reason it is provided is that the board space can be saved by placing digital switch in the 16-SOIC (0.209, 5.30mm Width).The package is in the form of Tube.digital switch ic uses the method of Surface Mount for mounting.Multiplexer is the analog IC that the multiplexers uses.The operating temperature of 0°C~70°C will not be susceptible to external factors.Design engineers have more flexibility when digital controlled switch operates at 4.5V~5.5V voltage.Since they are members of the 74F series, they can be used in a wide variety of applications.There are 16 terminations included in its basic configuration.In this case, 5V is the voltage supplied to the multiplexer's system.This turn signal switch consists of 16 component pins.As a result, conductors end at GULL WING.The logic switch is included into the family of F/FAST.To avoid unnecessary failures, keep the supply voltage at 4.5V (Vsup).Vsup (maximum supply voltage) should be kept as 5.5V to prevent unnecessary failures.In order for the turn signal switch to work, there are 1 outputs.There are 2 inputs provided in this multiplexer.
