SN74LVC257AD Overview


For the purpose of saving board space, digital switch is included in the 16-SOIC (0.154, 3.90mm Width).In this case, it is packaged as Tube.Digital switch ic uses a Surface Mount mounting method.As the analog part, the circuit uses an analog IC Multiplexer.A temperature of -40°C~85°C will not leave the turn signal swturn signal switchch susceptible to external influences.With a supply voltage of 1.65V~3.6V, designers have greater flexibility of digital controlled switch.As a member of 74LVC series, the multiplexers can be used for a wide range of applications.As part of its basic configuration, 16 terminations are designed as a part of it.There is a base part number 74LVC257 that can be used to locate signal switch's related components as well.The multiplexer's system is powered by 3.3V volts.A component pin count of 16 can be found on this turn signal switch.It employs GULL WING as the point at which conductors come to an end.As a type of supply, Single is employed.The board is configured with 16 pins.The mounting point is Surface Mount.The LVC/LCX/Z family includes the logic switch.Signal multiplexer contains 2 bits.It is advisable that the maximal supply voltage (Vsup) remains at 3.6V to avoid some unnecessary failures.For mux switch's normal operation, power supply 3.3V is provided.This turn signal switch has 1 outputs designed for its operation.Without any external influences, it consumes 10μA current of multiplexer ic at all times.This multiplexer has 8 inputs.This turn signal switch's circuit is based on a circuit with 4 channels.
