74ACT11257NSRE4 Overview
As a means of saving space, digital switch is provided in the 20-SOIC (0.209, 5.30mm Width).As a result, it is packaged in a way that is referred to as Tape & Reel (TR).Mounting is performed using Surface Mount.Multiplexer is the analog IC that the multiplexers uses.When the operating temperature is kept at -40°C~85°C, the machine will not be sensturn signal switchive to external influences.Designers have greater flexibility using digital controlled switch when it works with 4.5V~5.5V voltage.The multiplexers can be used for a wide range of applications since they are members of 74ACT series.There is a design for terminating 20 as part of its basic configuration.There is a base part number 74ACT11257 that can be used to locate signal switch's related components as well.The multiplexer's system is supplied with a voltage of 5V.In this turn signal switch, there are 20 component pins.It is the end of conductors that is represented by GULL WING.In this case, Dual is employed as the supply type.Currently, it is configured with 20 pins.The multiplexer ic is mounted in the direction of Surface Mount.The logic switch is included into the family of ACT.There are 4 bits in signal multiplexer.Vsup (maximum supply voltage) should be kept as 5.5V to prevent unnecessary failures.In order for 5V to operate normally, a power supply is provided.The turn signal switch operates with 1 outputs.According to TAPE AND REEL, the switches is packaged.As a voltage level input, the multiplexers have 2 lines.Additionally, CENTER VCC/GND PINS has improved characteristics.
