SN74HC257PW Overview
Due to the fact that it is provided in the 16-TSSOP (0.173, 4.40mm Width), digital switch allows the board to be compacted.The package is packaged in the manner of Tube.The method digital switch ic adopts for mounting is Surface Mount.The multiplexers uses an analog IC Multiplexer as the analog part of the circuit.Turn signal switch will not be susceptible to the external factors when the operating temperature is kept at -40°C~85°C.When digital controlled switch operates at 2V~6V, designers are provided with a greater degree of flexibility.With the 74HC series, the multiplexers are suitable for a diverse range of applications.There is a design for terminating 16 as part of its basic configuration.To find signal switch's related components, a base part number of 74HC257 may also be used.In multiplexer's system, 5V is the voltage supplied.In this turn signal switch, there are 16 component pins.As the end of conductors, it uses GULL WING.As a type of supply, Single is employed.Currently, it is configured with 16 pins.The multiplexer ic is mounted in the direction of Surface Mount.The logic switch belongs to the family of HC/UH.In this signal multiplexer, there are 2 bits that are provided.The minimal supply voltage (Vsup) should be kept at 2V to avoid some unnecessary failures.It is advisable to keep the maximum supply voltage (Vsup) at 6V in order to prevent some unnecessary failures.This turn signal switch has 1 outputs designed for its operation.The performance of the multiplexers of a system can be reliably achieved with a supply voltage of 5V.It has 8 inputs.A total of 4 channels are used for transmission in the turn signal switch's circuit.
