SN74LS139AD 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.Tube is the packaging method.Digital switch ic uses a Surface Mount mounting method.The analog IC used in the multiplexers can be referred to as Decoder/Demultiplexer.As long as the operating temperature is 0°C~70°C, turn signal switch will not be influenced by external factors.Design engineers have more flexibility when digital controlled switch operates at 4.75V~5.25V voltage.Several applications are possible for 74LS series multiplexers.As part of its basic configuration, 16 terminations are designed as a part of it.The part number for 74LS139 can be used to find its logic switch related parts as well.For multiplexer's system, a voltage of 5V is supplied.This turn signal switch has 16 component pins.Using the point GULL WING as an end point of conductors, it is used to determine the terminus of a conductor.This supply type employs Single.Currently, it is configured with 16 pins.This unit is mounted in the way of Surface Mount.In the LS family, the logic switch is included.In this signal multiplexer, there are 4 bits that are provided.In order for 5V to operate normally, a power supply is provided.As a result, the turn signal switch consists of 4 outputs.Part number Decoder/Drivers indicates that the digital switch ic is an electronic part.The performance of the multiplexers of a system can be reliably achieved with a supply voltage of 5V.Additionally, it improves the characteristics of SCHOTTKY CLAMPED FOR HIGH PERFORMANCE.To ensure that the digitalswitch performs properly, 2 circuits are formed.
