SN74AS157NSR Overview
Due to the fact that it is provided in the 16-SOIC (0.209, 5.30mm Width), digital switch allows the board to be compacted.The package is in the form of Tape & Reel (TR).For mounting, digital switch ic uses the method Surface Mount.the multiplexers uses an analog IC Multiplexer.When the operating temperature is kept at 0°C~70°C, the machine will not be sensturn signal switchive to external influences.When digital controlled switch operates at 4.5V~5.5V, designers are provided with a greater degree of flexibility.These multiplexers are members of the 74AS series, which provide extensive application potential.Among its basic configurations are 16 terminations.The multiplexer is supplied with 5V voltage.It is the end of conductors that is represented by GULL WING.The logic switch is a member of the family of AS.Vsup should be kept at 4.5V to prevent some unnecessary failures.To avoid unnecessary failures, the maximum supply voltage (Vsup) should be kept at 5.5V.As part of the operation of this turn signal switch, there are 1 outputs.This multiplexer is equipped with 2 inputs and 2 outputs.
