MC74ACT257MELG Overview
Digital switch is provided in the 16-SOIC (0.209, 5.30mm Width) for the purpose of saving board space.As a result, it is packaged in a way that is referred to as Tape & Reel (TR).Digital switch ic uses a Surface Mount mounting method.the multiplexers uses an analog IC Multiplexer.A temperature of -40°C~85°C will not leave the turn signal swturn signal switchch susceptible to external influences.When digital controlled switch operates at 4.5V~5.5V, designers are provided with a greater degree of flexibility.Multiplexers in the 74ACT series are suitable for a wide range of applications.Among its basic features are 16 terminations.There is a base part number 74ACT257 that can be used to locate signal switch's related components as well.The voltage supplied for multiplexer's system is 5V.multiplexer's systemSignal switch has 16 component pins.Conductors terminate at GULL WING in this design.There is a type of supply Single that is employed in this case.With 16 pins, it is configured.The multiplexer ic is mounted in the direction of Surface Mount.The logic switch belongs to the family of ACT.As a result, signal multiplexer provides a total of 4 bits.There is a power supply provided for the mux switch's normal operation of 5V.If the supply voltage is 5V, reliable performance of the multiplexers can be achieved.There are 8 inputs provided in this multiplexer.The switches package is packaged in accordance with TAPE AND REEL.It is possible to accept voltage levels through 2 input lines of multiplexers.A signal source has 3 output lines.
