74AC11257DWR Overview
It is included in the 20-SOIC (0.295, 7.50mm Width) in order to save board space.It is packaged in the way of Tape & Reel (TR).In terms of mounting, digital switch ic uses the method of Surface Mount.the multiplexers uses an analog IC Multiplexer.By keeping the operating temperature at -40°C~85°C, turn signal switch will not be affected by external factors.When operated with a 3V~5.5V supply voltage, digital controlled switch provides digital controlled switch's superior flexibility for designers.With the 74AC series, the multiplexers are suitable for a diverse range of applications.As part of its basic configuration, 20 terminations are designed as a part of it.You can also find related parts by using its logic switch base part number of 74AC11257.The multiplexer's system is powered by 5V volts.This turn signal switch contains 20 component pins.As a result, conductors end at GULL WING.Its supply type is Dual, which is used as the source of power.The board has 20 pins configured.It is positioned in the direction of Surface Mount.There is a family of AC members.As a result, signal multiplexer provides a total of 2 bits.To avoid unnecessary failures, keep the supply voltage at 3V (Vsup).It is advisable that the maximal supply voltage (Vsup) remains at 5.5V to avoid some unnecessary failures.For mux switch's normal operation, there is a power supply provided at 3.3/5V.As part of the operation of this turn signal switch, there are 1 outputs.It has 8 inputs.A TR packaging method is used in the switches.The turn signal switch's circuit consists of 4 channels that are being used for transmission in the circuit.In addition, it provides improved features of CENTER VCC/GND PINS.
