MC74LCX257DTR2 Overview
In order to save board space, digital switch is located in the 16-TSSOP (0.173, 4.40mm Width).In this case, it is packaged as Tape & Reel (TR).For mounting, digital switch ic uses the method Surface Mount.The analog IC used in the multiplexers can be referred to 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 2.3V~3.6V voltage.Multiplexers in the 74LCX series are suitable for a wide range of applications.As part of its basic configuration, 16 terminations are designed as a part of it.For multiplexer's system, 2.5V voltage is supplied.Signal switch has 16 component pins.Conductors terminate at GULL WING in this design.The LVC/LCX/Z family includes the logic switch.Vsup should be kept at 2V to prevent some unnecessary failures.Vsup (maximum supply voltage) should be kept as 3.6V to prevent unnecessary failures.The turn signal switch has 1 outputs designed for operation.This multiplexer is equipped with 2 inputs and 2 outputs.
