74AC11257DBRE4 Overview
Due to the fact that it is provided in the 20-SSOP (0.209, 5.30mm Width), digital switch allows the board to be compacted.It is packaged according to the Tape & Reel (TR) method.Mounting is performed using Surface Mount.Multiplexer is the analog IC that the multiplexers uses.As long as the operating temperature is -40°C~85°C, turn signal switch will not be influenced by external factors.It provides digital controlled switch's superior flexibility for designers to use when it operates with a supply voltage of 3V~5.5V.provides digital controlled switch's digital controlled switch'sMultiplexers from the 74AC series can be used in a wide range of applications.As parts of its basic configuration, 20 terminations are desgined.The base part number is 74AC11257, which can also be used to find its logic switch related parts.The multiplexer's system is supplied with a voltage of 5V.This turn signal switch consists of 20 component pins.As the end of conductors, it uses GULL WING.The supply type of this multiplexer ic is Dual.The board is configured with 20 pins.The mount is in Surface Mount.The AC family includes the logic switch.Signal multiplexer provides 4 bits.Keeping the minimum supply voltage (Vsup) at 3V prevents some unnecessary failures.It is advisable to keep the maximum supply voltage (Vsup) at 5.5V in order to prevent some unnecessary failures.The power supply of 3.3/5V is provided for mux switch's normal operation.The turn signal switch operates with 1 outputs.The signal switching is packaged by TAPE AND REEL. A voltage level can be inserted into the 2 input lines of multiplexers.
