DM74AS157N Overview
Due to the fact that it is provided in the 16-DIP (0.300, 7.62mm), digital switch allows the board to be compacted.In this case, it is packaged as Tube.The mounting method digital switch ic uses 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.With a supply voltage of 4.5V~5.5V, designers have greater flexibility of digital controlled switch.These multiplexers are members of the 74AS series, which provide extensive application potential.This configuration includes 16 terminations as part of its basic functionality.For multiplexer's system, 5V voltage is supplied.A component pin count of 16 can be found on this turn signal switch.The logic switch object belongs to the family of AS.In order to prevent unnecessary failures, it is recommended that the minimal supply voltage (Vsup) be kept at 4.5V.It is advisable that the maximal supply voltage (Vsup) remains at 5.5V to avoid some unnecessary failures.There are 1 outputs designed to operate the turn signal switch.It has 2 inputs.
