MC74AC257MEL Overview


In order to save board space, digital switch is located in the 16-SOIC (0.209, 5.30mm Width).The package is packaged in accordance with Tape & Reel (TR).In terms of mounting, digital switch ic uses the Surface Mount method .As the analog part, the circuit uses an analog IC Multiplexer.In the case of -40°C~85°C, turn signal switch will not be affected by external factors.When digital controlled switch operates at 2V~6V, designers have superior flexibility.Several applications are possible for 74AC series multiplexers.There are 16 terminations included in its basic configuration.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 volts.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.The logic switch is a member of the AC family.Vsup should be kept at 2V to prevent some unnecessary failures.It is advisable to keep the maximum supply voltage (Vsup) at 6V so as to avoid some unnecessary failures.Normally, 3.3/5V is powered by a battery.For the turn signal switch's operation, there are 1 outputs.The multiplexer provides 2 inputs.Currently, the switches is packaged in accordance with the TAPE AND REEL method.
