SN74HCT257D Overview
In order to save board space, digital switch is located in the 16-SOIC (0.154, 3.90mm Width).It is packaged according to the Tube method.The mounting method digital switch ic uses is Surface Mount.For the analog part of the multiplexers, an IC Multiplexer is used.When the operating temperature is kept at -40°C~85°C, turn signal switch will not be susceptible to external factors.Designers have greater flexibility when digital controlled switch operates at a 4.5V~5.5V supply voltage.Multiplexers in the 74HCT series are suitable 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 74HCT257 may also be used.For multiplexer's system, a voltage of 5V is supplied.A component pin count of 16 is found on this turn signal switch.GULL WING represents the end of conductors.In this case, the supply type is Single.This multiplexer ic has 16 pins configured.The mounting point is Surface Mount.The logic switch belongs to the family of HCT.In the signal multiplexer, there are 2 bits available.For mux switch's normal operation, power supply 5V is provided.As part of the operation of this turn signal switch, there are 1 outputs.If the supply voltage is 5V, reliable performance of the multiplexers can be achieved.This multiplexer has a total of 8 inputs.The turn signal switch's circuit has 4 transmission channels.
