CD40257BMG4 Product Details

CD40257BMG4 Overview


Due to the lack of space on the board, digital switch is provided in the SOIC.There are 16 terminations included in its basic configuration.In this case, 5V is the voltage supplied to the multiplexer's system.Signal switch has 16 component pins.GULL WING represents the end of conductors.There is a supply type of Dual employed as part of this supply.This multiplexer ic has 16 pins configured.As you can see, it is mounted in the direction of Surface Mount.There are no external influences on this multiplexer ic, so it consumes 40nA current.It is provided with 8 inputs.The switches package is packaged in a way which is consistent with TUBE.In order to accept voltage levels, the multiplexers have input lines 2 on the board.In this case, the signal source has a total of 1 output lines.This turn signal switch's circuit is based on a circuit with 4 channels.The signal switch can operate at a maximum temperature of 125°C.Maintaining a minimum operating temperature of the multiplexer of -55°C is recommended.The device is specified to operate at a maximum supply voltage of 18V in accordance with the applicable device specification.In compliance with the applicable device specification, the digital swith operates at a minimum supply voltage of 3V.
