SN74HC157DRE4 Product Details

SN74HC157DRE4 Overview


It is included in the SOIC in order to save board space.As a result, it is packaged in the way of Tape & Reel (TR).Among its basic features are 16 terminations.The multiplexer's system is powered by 5V volts.A component pin count of 16 can be found on this turn signal switch.GULL WING is used as the point at which the conductors come to an end as part of this formula.In this case, Single is employed as the supply type.There are 16 pins on it.The mount is in Surface Mount.Among the family of HC/UH the logic switch is a member.As a result, signal multiplexer provides 2 bits.This multiplexer has a total of 8 inputs.According to TR, the switches is packaged.It is possible to accept voltage levels through 2 input lines of multiplexers.Signal source consists of 1 output lines.Transmission is carried out over 4 channels in the turn signal switch's circuit.Signal switchs at temperatures up to 85°C are acceptable.It is recommended that the minimum operating temperature of the multiplexer be kept at -40°C.The relevant device specification specifies a maximum supply voltage of 6V for the signal switches.A minimum supply voltage of 2V is required to operate the digital swith.
