SN74CBT3245ADBQR Overview


For the purpose of saving board space, digital switch is included in the 20-SSOP (0.154, 3.90mm Width).It is packaged in the way of Cut Tape (CT).The method digital switch ic adopts for mounting is Surface Mount.In the multiplexers, the analog IC is indicated by Bus Switch.If the operating temperature is maintained at -40°C~85°C, turn signal switch will not be susceptible to external factors.With a supply voltage of 4V~5.5V, designers have greater flexibility of digital controlled switch.The multiplexers can be used for a wide range of applications since they are members of 74CBT series.Its basic configuration includes terminations in the 20 range.The base part number is 74CBT3245, which is also useful when looking up signal switch's related components.The turn signal switch is supplied with a voltage of 5V volts.Signal switch has 20 component pins.At the end of a conductor, it uses GULL WING as the point where the conductor ends.There is a type of supply of Single.Currently, it is configured with 20 pins.The mounting point is Surface Mount.There is a family of CBT/FST/QS/5C/B members.The multiplexer ic provides 8 bits.Keeping Vsup at 4V will prevent some unwanted failures.In order to maintain mux switch's normal operation, power is provided to 5V.Part number Bus Driver/Transceivers indicates that the digital switch ic is an electronic part.Without external influences, it consumes 50μA current of multiplexer ic.Using a supply voltage of 5V can result in reliable performance of the multiplexers.Currently, the switches is packaged in accordance with the TR method.A resistance of 2 is used to operate the signal switching.The system operates with a resistance of 7Ohm.In order to provide greater switches' flexibility, 64mA is provided as the output current.
