SN74ALS257ANSR Product Details

SN74ALS257ANSR Overview


Due to the lack of space on the board, digital switch is provided in the 16-SOIC (0.209, 5.30mm Width).It is packaged in the way of Tape & Reel (TR).In terms of mounting, digital switch ic uses the Surface Mount method .The analog IC in the multiplexers is identified as Multiplexer.By keeping the operating temperature at 0°C~70°C, turn signal switch will not be affected by external factors.The turn signal switch is designed for use with a 4.5V~5.5V supply voltage, which gives it a lot of flexibility.Since they are members of the 74ALS series, they can be used in a wide variety of applications.Its basic configuration includes terminations in the 16 range.There is a base part number of 74ALS257 which can also be used in order to locate the logic switch that are related to this item.For multiplexer's system, 5V voltage is supplied.This turn signal switch has 16 component pins.A conductor terminates at GULL WING.There is a type of supply Single that is employed in this case.A total of 16 pins are configured on this board.As you can see, it is mounted in the direction of Surface Mount.The ALS family includes the logic switch.Signal multiplexer provides 2 bits.In order for 5V to operate normally, a power supply is provided.As part of the operation of this turn signal switch, there are 1 outputs.Using a supply voltage of 5V can result in reliable performance of the multiplexers.It has 8 inputs.The switches package is packaged in accordance with TR.A total of 4 channels are used for transmission in the turn signal switch's circuit.
