74AC157TTR Overview
For the purpose of saving board space, digital switch is included in the 16-TSSOP (0.173, 4.40mm Width).The package is packaged in accordance with Tape & Reel (TR).In terms of mounting, digital switch ic uses the method of Surface Mount.the multiplexers uses an analog IC Multiplexer.When the operating temperature is kept at -55°C~125°C, the machine will not be sensturn signal switchive to external influences.Design engineers have more flexibility when digital controlled switch operates at 2V~6V voltage.The multiplexers from 74AC series can be used for a wide range of applications.As parts of its basic configuration, 16 terminations are desgined.The base part number is 74AC157, so you can find its logic switch related parts using that number.The turn signal switch is supplied with a voltage of 3.3V volts.Currently, this turn signal switch has a total of 16 component pins.At the end of a conductor, it uses GULL WING as the point where the conductor ends.In this case, Single is employed as the supply type.A total of 16 pins are configured on this board.It is mounted in the way of Surface Mount.I would like to refer to the logic switch as a member of the AC family.Keeping Vsup at 2V will prevent some unwanted failures.In order to avoid some unnecessary failures, you should maintain a maximum supply voltage (Vsup) of 6V.For mux switch's normal operation, power supply 3.3/5V is provided.The turn signal switch has 1 outputs.There are 8 inputs provided in this multiplexer.The signal switching is packaged by TAPE AND REEL. A normal operation of the digitalswitch requires 4 circuits.
