SN74HC257N Overview


For the purpose of saving board space, digital switch is included in the 16-DIP (0.300, 7.62mm).The package is in the form of Tube.Digital switch ic uses a Through Hole mounting method.the multiplexers 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.Designers have greater flexibility using digital controlled switch when it works with 2V~6V voltage.With the 74HC series, the multiplexers are suitable for a diverse range of applications.Its basic configuration includes terminations in the 16 range.To find signal switch's related components, a base part number of 74HC257 may also be used.In this case, 5V is the voltage supplied to the multiplexer's system.This turn signal switch has a total of 16 component pins.Single is employed as its supply type.It is configured with 16 pins.As you can see, it is mounted in the direction of Through Hole.The HC/UH family includes the logic switch.Signal multiplexer provides 2 bits.To prevent unnecessary failures, it is recommended that the minimum supply voltage (Vsup) remain at 2V.Vsup (maximum supply voltage) should be kept as 6V to prevent unnecessary failures.For the turn signal switch's operation, there are 1 outputs.Reliable performance of the multiplexers can be achieved when a supply voltage of 5V is provided.This multiplexer is equipped with 8 inputs and 8 outputs.The turn signal switch's circuit consists of 4 channels that are being used for transmission in the circuit.
