SN74HC257PWR Overview
In order to conserve board space, digital switch is included in the 16-TSSOP (0.173, 4.40mm Width).The package is packaged in the manner of Cut Tape (CT).In terms of mounting, digital switch ic uses the method of Surface Mount.Multiplexer is the analog IC that the multiplexers uses.As long as the operating temperature is -40°C~85°C, turn signal switch will not be influenced by external factors.When digital controlled switch operates at 2V~6V, designers are provided with a greater degree of flexibility.Multiplexers from the 74HC series can be used in a wide range of applications.It is designed with 16 terminations as part of its basic configuration.The part number for 74HC257 can be used to find its logic switch related parts as well.For multiplexer's system, 5V voltage is supplied.A component pin count of 16 is found on this turn signal switch.It employs GULL WING as the point at which conductors come to an end.In this case, the supply type is Single.It is configured with 16 pins.As you can see, it is mounted in the direction of Surface Mount.The logic switch is included into the family of HC/UH.The multiplexer ic provides 2 bits.To avoid unnecessary failures, keep the supply voltage at 2V (Vsup).Avoid unnecessary failures by keeping Vsup at 6V.For the turn signal switch's operation, there are 1 outputs.When a supply voltage of 5V is used, reliable performance of the multiplexers can be achieved.In this multiplexer, there is a total of 8 inputs.TR is used to package the switches.Transmission is carried out over 4 channels in the turn signal switch's circuit.
