SN74LS251N Overview
In order to conserve board space, digital switch is included in the 16-DIP (0.300, 7.62mm).As a result, it is packaged in the way of Tube.Mounting is performed using Through Hole.For the analog part of the multiplexers, an IC Multiplexer is used.The operating temperature of 0°C~70°C will not be susceptible to external factors.When operated with a 4.75V~5.25V supply voltage, digital controlled switch provides digital controlled switch's superior flexibility for designers.Multiplexers of the 74LS series can be used in a wide range of applications.Among its basic configurations are 16 terminations.In this case, 5V is the voltage supplied to the multiplexer's system.For mux switch's normal operation, there is a power supply provided at 5V.This multiplexer has a total of 8 inputs.
