N74F257AD,623 Overview
Due to the lack of space on the board, digital switch is provided in the 16-SOIC (0.154, 3.90mm Width).Tape & Reel (TR) is the packaging method.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 0°C~70°C, turn signal switch will not be susceptible to external factors.Designers have greater flexibility when digital controlled switch operates at a 4.5V~5.5V supply voltage.These multiplexers are members of the 74F series, which provide extensive application potential.Its basic configuration includes terminations in the 16 range.There is a base part number 74F257 that can be used to locate signal switch's related components as well.The multiplexer's system is powered by 5V voltage.There are 16 component pins in this turn signal switch.Using the point GULL WING as an end point of conductors, it is used to determine the terminus of a conductor.The logic switch is a member of the F/FAST family.To prevent unnecessary failures, it is recommended that the minimum supply voltage (Vsup) remain at 4.5V.It is advisable that the maximal supply voltage (Vsup) remains at 5.5V to avoid some unnecessary failures.During mux switch's normal operation, 5V is provided with a power supply.There are 1 outputs designed to operate the turn signal switch.This multiplexer has 2 inputs.According to TAPE AND REEL, the switches is packaged.
