CD40257BMT Overview


This is a relatively small item of digital switch that is included in the 16-SOIC (0.154, 3.90mm Width) in order to save space on the board.In this case, it is packaged as Tape & Reel (TR).Digital switch ic adheres to a mounting method of Surface Mount.A digital IC Multiplexer is used as the analog component of the multiplexers.A temperature of -55°C~125°C will not leave the turn signal swturn signal switchch susceptible to external influences.Designers have greater flexibility using digital controlled switch when it works with 3V~18V voltage.Several applications are possible for 4000B series multiplexers.As parts of its basic configuration, 16 terminations are desgined.The base part number is CD40257, which is also useful when looking up signal switch's related components.The multiplexer's system is supplied with a voltage of 5V.A component pin count of 16 can be found on this turn signal switch.Conductors terminate at GULL WING in this design.Its supply type is Dual, which is used as the source of power.It is configured with 16 pins.This unit is mounted in the way of Surface Mount.To prevent unnecessary failures, it is recommended that the minimum supply voltage (Vsup) remain at 3V.In order for the turn signal switch to work, there are 1 outputs.In this multiplexer, there is a total of 8 inputs.In accordance with TAPE AND REEL, switches can be packaged.It is possible to accept voltage levels by using one of the 2 input lines of multiplexers.A total of 4 transmission channels are available in the turn signal switch's circuit.
