SN74HC257DRG4 Overview


The reason it is provided is that the board space can be saved by placing digital switch in the SOIC.The package is packaged in the manner of Tape & Reel (TR).Among its basic features are 16 terminations.The voltage supplied for multiplexer's system is 5V.multiplexer's systemThis turn signal switch contains 16 component pins.It employs GULL WING as the point at which conductors come to an end.Single is employed as its supply type.A configuration of 16 pins is used.It is positioned in the direction of Surface Mount.In the HC/UH family, the logic switch is included.If the supply voltage is 5V, reliable performance of the multiplexers can be achieved.This multiplexer is equipped with 8 inputs and 8 outputs.A TAPE AND REEL packaging method is used in the switches.For the purpose of accepting voltage levels, the multiplexers have 2 input lines.The signal source consists of 1 output lines.A total of 4 transmission channels are available in the turn signal switch's circuit.At 85°C, the maximum operating temperature of this signal switch is acceptable.In order to maintain a minimal operating temperature of the multiplexer, it should be set at -40°C.According to the applicable device specification, the signal switches operates at a maximum supply voltage of 6V.According to the applicable specification, the digital swith should operate at a minimum supply voltage of 2V.
