SN74ALS257ADR Overview
Due to the fact that it is provided in the 16-SOIC (0.154, 3.90mm Width), digital switch allows the board to be compacted.Cut Tape (CT) is the method used for packaging.In terms of mounting, digital switch ic uses the Surface Mount method .In the multiplexers, the analog IC Multiplexer is used.The operating temperature of 0°C~70°C will not be susceptible to external factors.A supply voltage of 4.5V~5.5V provides digital controlled switch's superior flexibility for designers.With the 74ALS series, the multiplexers are suitable for a diverse range of applications.There is a design for terminating 16 as part of its basic configuration.In addition, it also has a base part number of 74ALS257, which can be used to find related parts.The turn signal switch is supplied with a voltage of 5V volts.Signal switch has 16 component pins.It employs GULL WING as the point at which conductors come to an end.This supply type employs Single.The board is configured with 16 pins.Surface Mount is the way it is mounted.The logic switch belongs to the family of ALS.As a result, signal multiplexer provides a total of 2 bits.In order for 5V to operate normally, a power supply is provided.There are 1 outputs designed for the operation of the turn signal switch.Despite not interacting with external factors, it consumes 9mA current of multiplexer ic.Supply voltages of 5V can provide reliable performance of the multiplexers.There are 8 inputs provided in this multiplexer.The switches packaging is based on TR.The turn signal switch's circuit has 4 transmission channels.
