74F257ASC Overview

The reason it is provided is that the board space can be saved by placing digital switch in the 16-SOIC (0.154, 3.90mm Width).The package is packaged in accordance with Tube.Digital switch ic adheres to a mounting method of Surface Mount.As the analog part, the circuit uses an analog IC Multiplexer.The operating temperature will not be affected by external factors when turn signal switch is set to 0°C~70°C.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.The basic configuration of this system includes 16 terminations.The multiplexer's system is supplied with a voltage of 5V.Currently, this turn signal switch has a total of 16 component pins.A conductor terminates at GULL WING.The logic switch object belongs to the family of F/FAST.Avoid unnecessary failures by keeping the supply voltage (Vsup) at 4.5V.To avoid some unnecessary failures, the maximum supply voltage (Vsup) should be kept at 5.5V.The turn signal switch contains 1 outputs designed to operate.A multiplexer such as this has 2 inputs available.
