SN74CBT3257DBQR Overview
For the purpose of saving board space, digital switch is included in the 16-SSOP (0.154, 3.90mm Width).Tape & Reel (TR) is the packaging method.For mounting, digital switch ic uses the method Surface Mount.A digital IC Multiplexer/Demultiplexer is used as the analog component of the multiplexers.In the case of -40°C~85°C, turn signal switch will not be affected by external factors.A supply voltage of 4.5V~5.5V provides digital controlled switch's superior flexibility for designers.Since they are members of the 74CBT series, they can be used in a wide variety of applications.Among its basic features are 16 terminations.As its base part number is 74CBT3257, logic switch can also be used to find its related parts.The voltage supplied for multiplexer's system is 5V.multiplexer's systemThis turn signal switch has a total of 16 component pins.It is the end of conductors that is represented by GULL WING.There is a type of supply of Single.This multiplexer ic has 16 pins configured.The mounting point is Surface Mount.There is a family of CBT/FST/QS/5C/B members.In this signal multiplexer, there are 8 bits that are provided.Keeping the minimum supply voltage (Vsup) at 4V prevents some unnecessary failures.In order to maintain mux switch's normal operation, power is provided to 5V.As a result, the turn signal switch consists of 2 outputs.Despite not interacting with external factors, it consumes 3μA current of multiplexer ic.With a supply voltage of 5V, reliable performance of the multiplexers can be achieved.The switches packaging is based on TR.A resistance of 7Ohm is used to operate the signal switching.For transmission, there are 4 channels in the turn signal switch's circuit.Furthermore, the characteristics of TTL COMPATIBLE MUX/DMUX SWITCH have been improved.Load stability of the multiplexers can be maintained by delivering 3μA supply voltage.
