74FST3257QSR Overview
As a means of saving space, digital switch is provided in the 16-SSOP (0.154, 3.90mm Width).The package is in the form of Tape & Reel (TR).digital switch ic uses the method of Surface Mount for mounting.Multiplexer/Demultiplexer is the analog IC that the multiplexers uses.By keeping the operating temperature at -40°C~85°C, turn signal switch will not be affected by external factors.When digital controlled switch operates at 4V~5.5V, designers are provided with a greater degree of flexibility.Since they are members of the 74FST series, they can be used in a wide variety of applications.The basic configuration includes 16 terminations.The part number for 74FST3257 can be used to find its logic switch related parts as well.The multiplexer's system is supplied with a voltage of 5V.There are 16 component pins in this turn signal switch.As the end of conductors, it uses GULL WING.In this case, the supply type is Single.The mount is in Surface Mount.The logic switch is a member of the CBT/FST/QS/5C/B family.In order to prevent unnecessary failures, it is recommended that the minimal supply voltage (Vsup) be kept at 4V.Keeping Vsup at 5.5V will prevent some unnecessary failures.For mux switch's normal operation, power supply 5V is provided.The turn signal switch contains 1 outputs designed to operate.In electronic terms, the digital switch ic is classified as Other Logic ICs.It is provided with 2 inputs.For the normal operation of the device, 4 circuits must be formed.
