SN74HC257DRG4 Product Details

SN74HC257DRG4 Overview


Providing this information in the SOIC enables digital switch board space to be saved.The package is in the form of Tape & Reel (TR).There is a design for terminating 16 as part of its basic configuration.The multiplexer's system works with 5V voltage.In this turn signal switch, there are 16 component pins.Conductors terminate at GULL WING in this design.The supply type of this multiplexer ic is Single.This multiplexer ic is configured with 16 pins.It is positioned in the direction of Surface Mount.In the HC/UH family, the logic switch is included.The performance of the multiplexers of a system can be reliably achieved with a supply voltage of 5V.In this multiplexer, there is a total of 8 inputs.TAPE AND REEL is used to package the switches.To accept voltage levels, the multiplexers have2 input lines.A signal source is provided by 1 output lines.A total of 4 channels are used for transmission in the turn signal switch's circuit.85°C is an acceptable maximum temperature for this signal switch.A temperature of the multiplexer of -40°C should be maintained for minimal operation.Based on the device specifications, the signal switches is designed to operate at 6V maximum supply voltage.A minimum supply voltage of 2V is specified for the digital swith by its applicable specification.
