74ACT11257DW Overview
In order to conserve board space, digital switch is included in the 20-SOIC (0.295, 7.50mm Width).It is packaged according to the Tube method.For mounting, digital switch ic uses the method Surface Mount.The analog IC used in the multiplexers can be referred to as Multiplexer.In the case of -40°C~85°C, turn signal switch will not be affected by external factors.When operated with a 4.5V~5.5V supply voltage, digital controlled switch provides digital controlled switch's superior flexibility for designers.These multiplexers are members of the 74ACT series, which provide extensive application potential.As part of its basic configuration, 20 terminations are designed as a part of it.The base part number is 74ACT11257, which is also useful when looking up signal switch's related components.The multiplexer's system works with 5V voltage.A component pin count of 20 can be found on this turn signal switch.It is the end of conductors that is represented by GULL WING.Dual is employed as its supply type.A configuration of 20 pins is used.The multiplexer ic is mounted in the direction of Surface Mount.Among the family of ACT the logic switch is a member.In this signal multiplexer, there are 2 bits provided.It is advisable to keep the maximum supply voltage (Vsup) at 5.5V so as to avoid some unnecessary failures.For mux switch's normal operation, power supply 5V is provided.In order for the turn signal switch to work, there are 1 outputs.In this multiplexer, there is a total of 8 inputs.In the turn signal switch's circuit, there are 4 channels used for transmission.Furthermore, the characteristics of CENTER VCC/GND PINS have been improved.
