74AC251SCX Product Details

74AC251SCX Overview


For the purpose of saving board space, digital switch is included in the 16-SOIC (0.154, 3.90mm Width).Tape & Reel (TR) represents its packaging.The method digital switch ic adopts for mounting is Surface Mount.The analog IC in the multiplexers is identified as Multiplexer.By keeping the operating temperature at -40°C~85°C, turn signal switch will not be affected by external factors.Design engineers have more flexibility when digital controlled switch operates at 2V~6V voltage.The multiplexers can be used for a wide range of applications since they are members of 74AC series.The part number for 74AC251 can be used to find its logic switch related parts as well.There is a supply type of Single employed as part of this supply.Currently, it is configured with a 16 pin configuration.The mounting point is Surface Mount.There are 1 bits signal multiplexer provides.There are 1 outputs designed to operate the turn signal switch.It is provided with 8 inputs.It is possible to accept voltage levels by using one of the 8 input lines of multiplexers.A signal source consists of 3 output lines.The turn signal switch's circuit consists of 1 transmission channels.There is no problem with operating this signal switch at the maximum temperature of 85°C.In order to maintain a minimal operating temperature, the temperature of the multiplexer should be set to -40°C.It is specified that the signal switches should operate at 6V as its maximum supply voltage.Device specifications require that the digital swith operate at a minimum supply voltage of 2V.
