SN74AS157N 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.Mounting is performed using Through Hole.A digital IC Multiplexer is used as the analog component of the multiplexers.When the operating temperature is kept at 0°C~70°C, turn signal switch will not be susceptible to external factors.Design engineers have more flexibility when digital controlled switch operates at 4.5V~5.5V voltage.Several applications are possible for 74AS series multiplexers.Its basic configuration includes terminations in the 16 range.The base part number is 74AS157, which is also useful when looking up signal switch's related components.In multiplexer's system, 5V is the voltage supplied.A component pin count of 16 is found on this turn signal switch.In this case, Single is employed as the supply type.A total of 16 pins are configured on this board.This unit is mounted in the way of Through Hole.Among the family of AS the logic switch is a member.Signal multiplexer provides 2 bits.Normally, 5V is powered by a battery.For the turn signal switch's operation, there are 1 outputs.If the supply voltage is set to 5V, reliable performance of the multiplexers can be achieved.It is provided with 8 inputs.This turn signal switch's circuit is based on a circuit with 4 channels.
