CD74HCT257MT Overview


In order to save board space, digital switch is located in the 16-SOIC (0.154, 3.90mm Width).Tape & Reel (TR) represents its packaging.digital switch ic uses the method of Surface Mount for mounting.The multiplexers uses an analog IC Multiplexer as the analog part of the circuit.If the operating temperature is maintained at -55°C~125°C, turn signal switch will not be susceptible to external factors.With a supply voltage of 4.5V~5.5V, designers have greater flexibility of digital controlled switch.The multiplexers from 74HCT series can be used for a wide range of applications.Among its basic features are 16 terminations.The base part number is 74HCT257, which can also be used to find its logic switch related parts.The multiplexer's system works with 5V voltage.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, the supply type is Single.Currently, it is configured with a 16 pin configuration.As you can see, it is mounted in the direction of Surface Mount.I would like to refer to the logic switch as a member of the HCT family.There are 4 bits signal multiplexer provides.During mux switch's normal operation, 5V is provided with a power supply.There are 1 outputs designed for the operation of the turn signal switch.Supply voltages of 5V can provide reliable performance of the multiplexers.This multiplexer has a total of 8 inputs.Currently, the switches is packaged in accordance with the TAPE AND REEL method.For the purpose of accepting voltage levels, the multiplexers have 2 input lines.
