SN74HCT257DR Overview
Due to the lack of space on the board, digital switch is provided in the 16-SOIC (0.154, 3.90mm Width).In this case, it is packaged as Cut Tape (CT).Surface Mount is the mounting method digital switch ic uses.the multiplexers uses IC Multiplexer as the analog IC.By maintaining the operating temperature at -40°C~85°C, turn signal switch will not be affected by external factors.It provides digital controlled switch's superior flexibility for designers to use when it operates with a supply voltage of 4.5V~5.5V.provides digital controlled switch's digital controlled switch'sSince they are members of the 74HCT series, they can be used in a wide variety of applications.This configuration includes 16 terminations as part of its basic functionality.As its base part number is 74HCT257, logic switch can also be used to find its related parts.The voltage supplied for multiplexer's system is 5V.multiplexer's systemCurrently, this turn signal switch has a total of 16 component pins.Using the point GULL WING as an end point of conductors, it is used to determine the terminus of a conductor.Single is employed as its supply type.The board is configured with 16 pins.The multiplexer ic is mounted in the direction of Surface Mount.The logic switch object belongs to the family of HCT.Signal multiplexer provides 2 bits.During mux switch's normal operation, 5V is provided with a power supply.As a result, the turn signal switch consists of 1 outputs.Using a supply voltage of 5V can result in reliable performance of the multiplexers.The multiplexer provides 8 inputs.The switches package is packaged in a way which is consistent with TR.The turn signal switch's circuit consists of 4 transmission channels.
