SN74LS156DR 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).Mounting is performed using Surface Mount.Decoder/Demultiplexer is the analog IC that the multiplexers uses.As long as the operating temperature is 0°C~70°C, turn signal switch will not be influenced by external factors.When digital controlled switch operates at 4.75V~5.25V, designers have superior flexibility.In addition to being a member of the 74LS series, these multiplexers have a wide range of applications.Its basic configuration includes terminations in the 16 range.The base part number is 74LS156, so you can find its logic switch related parts using that number.In this case, 5V is the voltage supplied to the multiplexer's system.A component pin count of 16 is found on this turn signal switch.As a result, conductors end at GULL WING.This supply type employs Single.A configuration of 16 pins is used.Surface Mount is the way it is mounted.I would like to refer to the logic switch as a member of the LS family.There are 4 bits in signal multiplexer.A power supply is provided for mux switch's normal operation of 5V.Part number Decoder/Drivers indicates that the digital switch ic is an electronic part.Supply voltages of 5V can provide reliable performance of the multiplexers.According to TR, the switches is packaged.This turn signal switch's circuit is based on a circuit with 2 channels.
