SN74ALS156DR Overview
For the purpose of saving board space, digital switch is included in the 16-SOIC (0.154, 3.90mm Width).Tape & Reel (TR) is the packaging method.Surface Mount is the mounting method digital switch ic uses.Decoder/Demultiplexer is the analog IC that the multiplexers uses.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.The multiplexers from 74ALS series can be used for a wide range of applications.Its basic configuration includes terminations in the 16 range.To find signal switch's related components, a base part number of 74ALS156 may also be used.The multiplexer's system is powered by 5V volts.In this turn signal switch, there are 16 components that can be connected to each pin.It is the end of conductors that is represented by GULL WING.This supply type employs Single.A total of 16 pins are configured on this board.This unit is mounted in the way of Surface Mount.In the ALS family, the logic switch is included.Signal multiplexer contains 8 bits.I would classify the digital switch ic as an electronic part belonging to the Decoder/Drivers category.When a supply voltage of 5V is used, reliable performance of the multiplexers can be achieved.A TR packaging method is used in the switches.In order to accept voltage levels, the multiplexers have input lines 2 on the board.Signal source consists of 4 output lines.A total of 12 transmission channels are available in the turn signal switch's circuit.
