SN74HCT157DRG4 Overview
It is included in the 16-SOIC (0.154, 3.90mm Width) in order to save board space.As a result, it is packaged in a way that is referred to as Tape & Reel (TR).As far as mounting is concerned, digital switch ic uses Surface Mount.The multiplexers uses an analog IC Multiplexer as the analog part of the circuit.The operating temperature of -40°C~85°C will not be susceptible to external factors.Design engineers have more flexibility when digital controlled switch operates at 4.5V~5.5V voltage.As a member of 74HCT series, the multiplexers can be used for 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 74HCT157 may also be used.The turn signal switch is supplied with a voltage of 5V volts.This turn signal switch has 16 component pins.As a result, GULL WING represents the end of the conductors.The supply type of this multiplexer ic is Single.A configuration of 16 pins is used.The multiplexer ic is mounted in the direction of Surface Mount.I would like to refer to the logic switch as a member of the HCT family.In the signal multiplexer, there are 2 bits available.It is advisable to keep the maximum supply voltage (Vsup) at 5.5V in order to prevent some unnecessary failures.For mux switch's normal operation, power supply 5V is provided.The turn signal switch has 1 outputs.This multiplexer provides 8 inputs.The switches is packaged according to the way of TR.A total of 4 transmission channels are available in the turn signal switch's circuit.
