SN74AS257D Overview

For the purpose of saving board space, digital switch is included in the 16-SOIC (0.154, 3.90mm Width).Tube represents its packaging.In terms of mounting, digital switch ic uses the method of Surface Mount.For the analog part of the multiplexers, an IC Multiplexer is used.By keeping the operating temperature at 0°C~70°C, turn signal switch will not be affected by external factors.Using a 4.5V~5.5V supply voltage provides digital controlled switch's superior flexibility for designers.Multiplexers of the 74AS series can be used in a wide range of applications.Its basic configuration includes terminations in the 16 range.The base part number is 74AS257, which is also useful when looking up signal switch's related components.The voltage supplied for multiplexer's system is 5V.multiplexer's systemThis turn signal switch has a total of 16 component pins.A conductor terminates at GULL WING.The supply type of this multiplexer ic is Single.A total of 16 pins are configured on this board.It is positioned in the direction of Surface Mount.The logic switch is included into the family of AS.In the signal multiplexer, there are 2 bits available.During mux switch's normal operation, 5V is provided with a power supply.As a result, the turn signal switch consists of 1 outputs.The performance of the multiplexers of a system can be reliably achieved with a supply voltage of 5V.There are 8 inputs provided in this multiplexer.For transmission, there are 4 channels in the turn signal switch's circuit.
