extent, the sales manager is going to reconfirm the order and let you know if there
are any updates.
Shipping Cost
Shipping starts at $40, but some countries will exceed $40. For
example (South Africa, Brazil, India, Pakistan, Israel, etc.)
The
basic freight (for package ≤0.5kg or corresponding volume) depends on the time zone and
country.
Currently, our products are shipped through DHL, FedEx, SF, and UPS.
Delivery TimeOnce the goods are shipped, estimated delivery time depends on the shipping methods you chose:
FedEx International, 5-7 business days.

SN74F257N Overview
The reason it is provided is that the board space can be saved by placing digital switch in the 16-DIP (0.300, 7.62mm).Tube is the packaging method.Mounting is performed using Through Hole.As the analog part, the circuit uses an analog IC Multiplexer.The operating temperature of 0°C~70°C will not be susceptible to external factors.When digital controlled switch operates at 4.5V~5.5V, designers are provided with a greater degree of flexibility.Multiplexers of the 74F series can be used in a wide range of applications.The basic configuration includes 16 terminations.There is a base part number 74F257 that can be used to locate signal switch's related components as well.For multiplexer's system, 5V voltage is supplied.A component pin count of 16 is found on this turn signal switch.There is a type of supply Single that is employed in this case.There are 16 pins on it.Multiplexer ics are mounted in the direction of Through Hole.The logic switch is included into the family of F/FAST.As a result, signal multiplexer provides 4 bits.It is provided that 5V has a power supply in order to function normally.The turn signal switch has 1 outputs.It consumes 15mA current of multiplexer ic without external influences.If the supply voltage is set to 5V, reliable performance of the multiplexers can be achieved.The multiplexer provides 8 inputs.To accept voltage levels, the multiplexers have2 input lines.It is necessary for the digitalswitch to operate normally that 4 circuits be formed.
