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.
The following are some common countries' logistic time.

74ACT11257PW Overview
As a means of saving space, digital switch is provided in the 20-TSSOP (0.173, 4.40mm Width).Tube is the method used for packaging.The method digital switch ic adopts for mounting is Surface Mount.Multiplexer is the analog IC that the multiplexers uses.Turn signal switch will not be susceptible to the external factors when the operating temperature is kept at -40°C~85°C.A supply voltage of 4.5V~5.5V provides digital controlled switch's superior flexibility for designers.These multiplexers are members of the 74ACT series, which provide extensive application potential.There is a design for terminating 20 as part of its basic configuration.Its logic switch base part number is 74ACT11257 which can also be used to find its logic switch related parts.In this case, 5V is the voltage supplied to the multiplexer's system.This turn signal switch has 20 component pins.GULL WING represents the end of conductors.There is a supply type of Dual employed as part of this supply.With 20 pins, it is configured.It is mounted in the way of Surface Mount.The ACT family includes the logic switch.Signal multiplexer contains 2 bits.To avoid some unnecessary failures, the maximum supply voltage (Vsup) should be kept at 5.5V.In order for 5V to operate normally, a power supply is provided.The turn signal switch has 1 outputs designed for operation.This multiplexer provides 8 inputs.The turn signal switch's circuit has 4 transmission channels.The characteristics of CENTER VCC/GND PINS are also improved.
