74AC11257DBR Overview
Providing this information in the 20-SSOP (0.209, 5.30mm Width) enables digital switch board space to be saved.It is packaged in the way of Tape & Reel (TR).The mounting method digital switch ic uses is Surface Mount.the multiplexers uses IC Multiplexer as the analog IC.In the case of -40°C~85°C, turn signal switch will not be affected by external factors.With a supply voltage of 3V~5.5V, designers have greater flexibility of digital controlled switch.Since they are members of the 74AC series, they can be used in a wide variety of applications.Among its basic configurations are 20 terminations.You can also find related parts by using its logic switch base part number of 74AC11257.The voltage supplied for multiplexer's system is 5V.multiplexer's systemIn this turn signal switch, there are 20 component pins.As a result, GULL WING represents the end of the conductors.This supply type employs Dual.The board has 20 pins configured.Surface Mount is the way it is mounted.The logic switch is a member of the family of AC.There are 4 bits signal multiplexer provides.Avoid unnecessary failures by keeping the supply voltage (Vsup) at 3V.It is advisable that the maximal supply voltage (Vsup) remains at 5.5V to avoid some unnecessary failures.In order to maintain mux switch's normal operation, power is provided to 3.3/5V.The turn signal switch has 1 outputs.According to TAPE AND REEL, the switches is packaged.A voltage level can be inserted into the 2 input lines of multiplexers.
