DM74ALS257N 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 a way that is referred to as Tube.The method digital switch ic adopts for mounting is Through Hole.In the multiplexers, the analog IC is indicated by Multiplexer.The operating temperature will not be affected by external factors when turn signal switch is set to 0°C~70°C.A supply voltage of 4.5V~5.5V provides digital controlled switch's superior flexibility for designers.These multiplexers are members of the 74ALS series, which provide extensive application potential.Its basic configuration includes terminations in the 16 range.The voltage supplied for multiplexer's system is 5V.multiplexer's systemThis turn signal switch contains 16 component pins.The logic switch is a member of the ALS family.To prevent unnecessary failures, it is recommended that the minimum supply voltage (Vsup) remain at 4.5V.It is advisable to keep the maximum supply voltage (Vsup) at 5.5V in order to prevent some unnecessary failures.The turn signal switch contains 1 outputs designed to operate.This multiplexer has a total of 2 inputs.
