74HCT257D,652 Overview


In order to conserve board space, digital switch is included in the 16-SOIC (0.154, 3.90mm Width).As a result, it is packaged in a way that is referred to as Tube.Digital switch ic adheres to a mounting method of Surface Mount.As the analog part, the circuit uses an analog IC Multiplexer.By keeping the operating temperature at -40°C~125°C, turn signal switch will not be affected by external factors.When digital controlled switch operates at 4.5V~5.5V, designers are provided with a greater degree of flexibility.Since they are members of the 74HCT series, they can be used in a wide variety of applications.As part of its basic configuration, 16 terminations are designed as a part of it.The base part number is 74HCT257, which is also useful when looking up signal switch's related components.In multiplexer's system, 5V is the voltage supplied.This turn signal switch has a total of 16 component pins.At the end of a conductor, it uses GULL WING as the point where the conductor ends.There is a supply type of Single employed as part of this supply.It is configured with 16 pins.It is positioned in the direction of Surface Mount.The HCT family includes the logic switch.The performance of the multiplexers of a system can be reliably achieved with a supply voltage of 5V.On the multiplexers, 8 input lines are provided for accepting voltage levels.Signal sources consist of output lines of 4.
