MC74AC257MELG Overview


The reason it is provided is that the board space can be saved by placing digital switch in the 16-SOIC (0.209, 5.30mm Width).In this case, it is packaged as Tape & Reel (TR).In terms of mounting, digital switch ic uses the method of Surface Mount.Multiplexer is the analog IC that the multiplexers uses.When the operating temperature is kept at -40°C~85°C, turn signal switch will not be susceptible to external factors.Using a 2V~6V supply voltage provides digital controlled switch's superior flexibility for designers.Multiplexers of the 74AC series can be used in a wide range of applications.Among its basic features are 16 terminations.The part number for 74AC257 can be used to find its logic switch related parts as well.The multiplexer's system is powered by 5V voltage.This turn signal switch contains 16 component pins.GULL WING is used as the point at which the conductors come to an end as part of this formula.Single is employed as its supply type.This multiplexer ic is configured with 16 pins.Multiplexer ics are mounted in the direction of Surface Mount.The AC family includes the logic switch.In this signal multiplexer, there are 4 bits provided.It is recommended that the minimum supply voltage (Vsup) be kept at 2V so that unnecessary failures can be prevented.It is advisable to keep the maximum supply voltage (Vsup) at 6V in order to prevent some unnecessary failures.Supply voltages of 5V can provide reliable performance of the multiplexers.In this multiplexer, there is a total of 8 inputs.The switches is packaged according to the way of TAPE AND REEL.It is possible to accept voltage levels through 2 input lines of multiplexers.A signal source consists of 3 output lines.
