SN74HC257NSR Overview
As a means of saving space, digital switch is provided in the 16-SOIC (0.209, 5.30mm Width).Cut Tape (CT) is the method used for packaging.In terms of mounting, digital switch ic uses the Surface Mount method .As the analog part, the circuit uses an analog IC Multiplexer.In the case of -40°C~85°C, turn signal switch will not be affected by external factors.Designers have greater flexibility when digital controlled switch operates at a 2V~6V supply voltage.The multiplexers can be used for a wide range of applications since they are members of 74HC series.The basic configuration includes 16 terminations.There is a base part number 74HC257 that can be used to locate signal switch's related components as well.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.As a type of supply, Single is employed.A total of 16 pins are configured on this board.The mounting is in the way of Surface Mount.The logic switch object belongs to the family of HC/UH.There are 2 bits signal multiplexer provides.Vsup should be kept at 2V to prevent some unnecessary failures.It is advisable to keep the maximum supply voltage (Vsup) at 6V so as to avoid some unnecessary failures.The turn signal switch has 1 outputs.It is possible to achieve reliable performance of the multiplexers with a voltage supply of 5V.This multiplexer has a total of 8 inputs.TR is used to package the switches.There are a total of 4 channels used for transmitting data in the turn signal switch's circuit.
