SN74F257DG4 Product Details

SN74F257DG4 Overview


Providing this information in the SOIC enables digital switch board space to be saved.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 F/FAST family, the logic switch is included.The multiplexer ic provides 4 bits.Normally, 5V is powered by a battery.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.To accept voltage levels, the multiplexers have2 input lines.A signal source is provided by 1 output lines.70°C is an acceptable maximum temperature for this signal switch.A temperature of the multiplexer of 0°C should be maintained for minimal operation.Based on the device specifications, the signal switches is designed to operate at 5.5V maximum supply voltage.A minimum supply voltage of 4.5V is specified for the digital swith by its applicable specification.
