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.

74F257ASCX Overview
Due to the lack of space on the board, digital switch is provided in the 16-SOIC (0.154, 3.90mm Width).The package is packaged in accordance with Tape & Reel (TR).In terms of mounting, digital switch ic uses the Surface Mount method .Multiplexer is the analog IC that the multiplexers uses.When the operating temperature is kept at 0°C~70°C, turn signal switch 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 in the 74F series are suitable for a wide range of applications.There are 16 terminations included in its basic configuration.The multiplexer is supplied with 5V voltage.This turn signal switch contains 16 component pins.As the end of conductors, it uses GULL WING.The logic switch is a member of the F/FAST family.Avoid unnecessary failures by keeping the supply voltage (Vsup) at 4.5V.Vsup (maximum supply voltage) should be kept as 5.5V to prevent unnecessary failures.The turn signal switch contains 1 outputs designed to operate.This multiplexer is equipped with 2 inputs and 2 outputs.
