74AHCT257D,118 Overview


The reason it is provided is that the board space can be saved by placing digital switch in the 16-SOIC (0.154, 3.90mm Width).Tape & Reel (TR) represents its packaging.Digital switch ic adheres to a mounting method of Surface Mount.The analog IC used in the multiplexers can be referred to as Multiplexer.The operating temperature of -40°C~125°C will not be susceptible to external factors.When digital controlled switch operates at 4.5V~5.5V, designers are provided with a greater degree of flexibility.Since they are members of the 74AHCT series, they can be used in a wide variety of applications.Among its basic configurations are 16 terminations.The base part number is 74AHCT257, so you can find its logic switch related parts using that number.For multiplexer's system, a voltage of 5V is supplied.A component pin count of 16 is found on this turn signal switch.As the end of conductors, it uses GULL WING.The supply type of this multiplexer ic is Single.Currently, it is configured with 16 pins.It is mounted in the way of Surface Mount.Among the family of AHCT/VHCT/VT the logic switch is a member.If the supply voltage is 5V, reliable performance of the multiplexers can be achieved.On the multiplexers, 8 input lines are provided for accepting voltage levels.As a signal source, there are 4 output lines.
