74LCX157TTR Overview


This is a relatively small item of digital switch that is included in the 16-TSSOP (0.173, 4.40mm Width) in order to save space on the board.Tape & Reel (TR) is the method used for packaging.In terms of mounting, digital switch ic uses the method of Surface Mount.For the analog part of the multiplexers, an IC Multiplexer is used.By maintaining the operating temperature at -40°C~85°C, turn signal switch will not be affected by external factors.Designers have greater flexibility using digital controlled switch when it works with 2V~3.6V voltage.Multiplexers from the 74LCX series can be used in a wide range of applications.As part of its basic configuration, 16 terminations are designed as a part of it.To find signal switch's related components, a base part number of 74LCX157 may also be used.The turn signal switch is supplied with a voltage of 2.7V volts.In this turn signal switch, there are 16 components that can be connected to each pin.It is the end of conductors that is represented by GULL WING.There is a type of supply Single that is employed in this case.The board is configured with 16 pins.Multiplexer ics are mounted in the direction of Surface Mount.The logic switch is a member of the family of LVC/LCX/Z.Keep Vsup at 2V to avoid unnecessary failures.It is advisable to keep the maximum supply voltage (Vsup) at 3.6V in order to prevent some unnecessary failures.There is a power supply provided for the mux switch's normal operation of 3.3V.There are 1 outputs designed to operate the turn signal switch.This multiplexer is equipped with 8 inputs and 8 outputs.The signal switching is packaged by TAPE AND REEL. Normally, the digitalswitch consists of 4 circuits.
