SN74AS257DRE4 Overview
The reason it is provided is that the board space can be saved by placing digital switch in the 16-SOIC (0.154, 3.90mm Width).It is packaged according to the Tape & Reel (TR) method.digital switch ic uses the method of Surface Mount for mounting.As the analog part, the circuit uses an analog IC Multiplexer.In the case of 0°C~70°C, turn signal switch will not be affected by external factors.A supply voltage of 4.5V~5.5V provides digital controlled switch's superior flexibility for designers.The multiplexers from 74AS series can be used for a wide range of applications.Among its basic configurations are 16 terminations.As its base part number is 74AS257, logic switch can also be used to find its related parts.The turn signal switch is supplied with a voltage of 5V volts.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.There is a supply type of Single employed as part of this supply.This multiplexer ic is configured with 16 pins.Multiplexer ics are mounted in the direction of Surface Mount.The logic switch is included into the family of AS.There are 4 bits in signal multiplexer.It is advisable that the maximal supply voltage (Vsup) remains at 5.5V to avoid some unnecessary failures.In order for 5V to operate normally, a power supply is provided.This turn signal switch has 1 outputs designed for its operation.The switches package is packaged in accordance with TAPE AND REEL.For the purpose of accepting voltage levels, the multiplexers have 2 input lines.
