SN74LS257BN Overview
For the purpose of saving board space, digital switch is included in the 16-DIP (0.300, 7.62mm).Tube is the packaging method.Mounting is performed using Through Hole.the multiplexers uses IC Multiplexer as the analog IC.By maintaining the operating temperature at 0°C~70°C, turn signal switch will not be affected by external factors.When digital controlled switch operates at 4.75V~5.25V, designers are provided with a greater degree of flexibility.These multiplexers are members of the 74LS series, which provide extensive application potential.Among its basic features are 16 terminations.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.The logic switch belongs to the family of LS.It is recommended that the minimum supply voltage (Vsup) be kept at 4.75V to avoid some unnecessary failures.The maximal supply voltage (Vsup) should be kept at 5.25V to avoid some unnecessary failures.The turn signal switch operates with 1 outputs.This multiplexer is equipped with 2 inputs and 2 outputs.
