SN74CBT3245CDBQR Product Details
SN74CBT3245CDBQR Overview
This is a relatively small item of digital switch that is included in the 20-SSOP (0.154, 3.90mm Width) in order to save space on the board.The package is packaged in the manner of Tape & Reel (TR).The method digital switch ic adopts for mounting is Surface Mount.The multiplexers uses an analog IC Bus Switch as the analog part of the circuit.Turn signal switch will not be susceptible to the external factors when the operating temperature is kept at -40°C~85°C.Designers have greater flexibility when digital controlled switch operates at a 4V~5.5V supply voltage.In addition to being a member of the 74CBT series, these multiplexers have a wide range of applications.The basic configuration of this system includes 20 terminations.To find signal switch's related components, a base part number of 74CBT3245 may also be used.For multiplexer's system, a voltage of 5V is supplied.This turn signal switch has 20 component pins.Using the point GULL WING as an end point of conductors, it is used to determine the terminus of a conductor.Single is used as its supply type.The board is configured with 20 pins.As you can see, it is mounted in the direction of Surface Mount.The logic switch is included into the family of CBT/FST/QS/5C/B.As a result, signal multiplexer provides 8 bits.It is recommended that the minimum supply voltage (Vsup) be kept at 4V to avoid some unnecessary failures.In order for 5V to operate normally, a power supply is provided.I would classify the digital switch ic as an electronic part belonging to the Bus Driver/Transceivers category.In the absence of external influences, it consumes 3μA current of multiplexer ic.The performance of the multiplexers of a system can be reliably achieved with a supply voltage of 5V.The signal switching is packaged by TR. 2 ports are used for some other peripheral signal switchings to plug in.In terms of resistance, it has a value of 12Ohm.It is possible to provide a current output of 64mA for greater switches' flexibility.
