MC74HC157ADTR2 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 packaging method.Digital switch ic adheres to a mounting method of Surface Mount.In the multiplexers, the analog IC is indicated by Data Selector/Multiplexer.Turn signal switch will not be susceptible to the external factors when the operating temperature is kept at -55°C~125°C.With a supply voltage of 2V~6V, designers have greater flexibility of digital controlled switch.Multiplexers of the 74HC series can be used in a wide range of applications.The basic configuration of this system includes 16 terminations.In addition, it also has a base part number of 74HC157, which can be used to find related parts.For multiplexer's system, 3V voltage is supplied.A component pin count of 16 is found on this turn signal switch.As a result, GULL WING represents the end of the conductors.Its supply type is Single, which is used as the source of power.This multiplexer ic has 16 pins configured.It is positioned in the direction of Surface Mount.In the HC/UH family, the logic switch is included.Keep Vsup at 2V to avoid unnecessary failures.It is advisable to keep the maximum supply voltage (Vsup) at 6V so as to avoid some unnecessary failures.This is an the digital switch ic that is classified as Multiplexer/Demultiplexers.The multiplexer is equipped with 8 inputs.TAPE AND REEL is used to package the switches.It is possible to accept voltage levels through 2 input lines of multiplexers.Signal sources consist of output lines of 4.
