CD74AC257M Overview
For the purpose of saving board space, digital switch is included in the 16-SOIC (0.154, 3.90mm Width).It is packaged in the way of Tube.Mounting is performed using Surface Mount.Multiplexer is the analog IC that the multiplexers uses.By maintaining the operating temperature at -55°C~125°C, turn signal switch will not be affected by external factors.Designers have greater flexibility using digital controlled switch when it works with 1.5V~5.5V voltage.These multiplexers are members of the 74AC series, which provide extensive application potential.Among its basic configurations are 16 terminations.There is a base part number 74AC257 that can be used to locate signal switch's related components as well.The multiplexer's system is powered by 3.3V volts.A component pin count of 16 is found on this turn signal switch.GULL WING is used as the point at which the conductors come to an end as part of this formula.There is a type of supply Single that is employed in this case.Currently, it is configured with 16 pins.Multiplexer ics are mounted in the direction of Surface Mount.In the AC family, the logic switch is included.In this signal multiplexer, there are 2 bits provided.To avoid unnecessary failures, the maximum supply voltage (Vsup) should be kept at 5.5V.It is provided that 3.3/5V has a power supply in order to function normally.The turn signal switch has 1 outputs designed for operation.In this multiplexer, there is a total of 8 inputs.For greater switches' flexibility, 75mA provides the output current.
