MC74AC257N Overview


Digital switch is provided in the 16-DIP (0.300, 7.62mm) for the purpose of saving board space.In this case, it is packaged as Tube.Through Hole is the mounting method digital switch ic uses.The multiplexers uses an analog IC Multiplexer as the analog part of the circuit.A temperature of -40°C~85°C will not leave the turn signal swturn signal switchch susceptible to external influences.Using a 2V~6V supply voltage provides digital controlled switch's superior flexibility for designers.Several applications are possible for 74AC series multiplexers.The basic configuration of this system includes 16 terminations.You can also find related parts by using its logic switch base part number of 74AC257.The voltage supplied for multiplexer's system is 5V.multiplexer's systemA component pin count of 16 is found on this turn signal switch.Its supply type is Single, which is used as the source of power.It is configured with 16 pins.Through Hole is the way it is mounted.There is a family of AC members.Signal multiplexer contains 4 bits.Avoid unnecessary failures by keeping the supply voltage (Vsup) at 2V.It is advisable to keep the maximum supply voltage (Vsup) at 6V so as to avoid some unnecessary failures.A voltage level can be inserted into the 2 input lines of multiplexers.A signal source is provided by 3 output lines.
