74AC257SC Overview


Providing this information in the 16-SOIC (0.154, 3.90mm Width) enables digital switch board space to be saved.As a result, it is packaged in a way that is referred to as Tube.In terms of mounting, digital switch ic uses the Surface Mount method .For the analog part of the multiplexers, an IC Multiplexer is used.When the operating temperature is kept at -40°C~85°C, the machine will not be sensturn signal switchive to external influences.When digital controlled switch operates at 2V~6V, designers have superior flexibility.Several applications are possible for 74AC series multiplexers.To find signal switch's related components, a base part number of 74AC257 may also be used.There is a type of supply Single that is employed in this case.The board is configured with 16 pins.As you can see, it is mounted in the direction of Surface Mount.In this signal multiplexer, there are 4 bits that are provided.The turn signal switch has 4 outputs.The multiplexer is equipped with 8 inputs.For the purpose of accepting voltage levels, the multiplexers have 2 input lines.As the signal source, there are 3 output lines.A maximum temperature of 85°C is acceptable for this signal switch.It is recommended that the minimum operating temperature of the multiplexer be kept at -40°C.The relevant device specification specifies a maximum supply voltage of 6V for the signal switches.A minimum supply voltage of 2V is specified for the digital swith by its applicable specification.A normal operation of the digitalswitch requires 4 circuits.
