SN74LS251NSR Product Details

SN74LS251NSR Overview


It is included in the 16-SOIC (0.209, 5.30mm Width) in order to save board space.The package is packaged in the manner of Tape & Reel (TR).Mounting is performed using Surface Mount.In the multiplexers, the analog IC Multiplexer is used.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.These multiplexers are members of the 74LS series, which provide extensive application potential.There are 16 terminations included in its basic configuration.There is a base part number of 74LS251 which can also be used in order to locate the logic switch that are related to this item.In this case, 5V is the voltage supplied to the multiplexer's system.There are 16 component pins in this turn signal switch.Using the point GULL WING as an end point of conductors, it is used to determine the terminus of a conductor.In this case, Single is employed as the supply type.There are 16 pins on it.This unit is mounted in the way of Surface Mount.The logic switch object belongs to the family of LS.In this signal multiplexer, there are 8 bits provided.In order for 5V to operate normally, a power supply is provided.The turn signal switch operates with 1 outputs.The performance of the multiplexers of a system can be reliably achieved with a supply voltage of 5V.This multiplexer has 8 inputs.The switches package is packaged in a way which is consistent with TR.
