MC74AC257NG Overview
In order to save board space, digital switch is located in the 16-DIP (0.300, 7.62mm).Tube represents its packaging.The method digital switch ic adopts for mounting is Through Hole.In the multiplexers, the analog IC Multiplexer is used.In the case of -40°C~85°C, turn signal switch will not be affected by external factors.Designers have greater flexibility when digital controlled switch operates at a 2V~6V supply voltage.Multiplexers of the 74AC series can be used in a wide range of applications.As parts of its basic configuration, 16 terminations are desgined.You can also find related parts by using its logic switch base part number of 74AC257.For multiplexer's system, 5V voltage is supplied.Signal switch has 16 component pins.In this case, the supply type is Single.It is configured with 16 pins.Through Hole is the way it is mounted.The logic switch is a member of the AC family.As a result, signal multiplexer provides a total of 4 bits.Keep Vsup at 2V to avoid unnecessary failures.The maximal supply voltage (Vsup) should be kept at 6V to avoid some unnecessary failures.Supply voltages of 5V can provide reliable performance of the multiplexers.It is provided with 8 inputs.To accept voltage levels, the multiplexers have2 input lines.As the signal source, there are 3 output lines.
