SN74HC257DT Overview
This is a relatively small item of digital switch that is included in the 16-SOIC (0.154, 3.90mm Width) in order to save space on the board.The package is in the form of Tape & Reel (TR).Mounting is performed using Surface Mount.In the multiplexers, the analog IC Multiplexer is used.When the operating temperature is kept at -40°C~85°C, the machine will not be sensturn signal switchive to external influences.When operated with a 2V~6V supply voltage, digital controlled switch provides digital controlled switch's superior flexibility for designers.With the 74HC series, the multiplexers are suitable for a diverse range of applications.Its basic configuration includes terminations in the 16 range.In addition, it also has a base part number of 74HC257, which can be used to find related parts.For multiplexer's system, 5V voltage is supplied.In this turn signal switch, there are 16 component pins.GULL WING represents the end of conductors.As a type of supply, Single is employed.Currently, it is configured with a 16 pin configuration.The mounting point is Surface Mount.The logic switch is a member of the HC/UH family.In this signal multiplexer, there are 2 bits that are provided.To prevent unnecessary failures, it is recommended that the minimum supply voltage (Vsup) remain at 2V.It is advisable to keep the maximum supply voltage (Vsup) at 6V in order to prevent some unnecessary failures.The turn signal switch contains 1 outputs designed to operate.This multiplexer provides 8 inputs.In accordance with TR, switches can be packaged.For transmission, there are 4 channels in the turn signal switch's circuit.
