74AC11257DW Overview
It is included in the 20-SOIC (0.295, 7.50mm Width) in order to save board space.The package is packaged in the manner of Tube.Digital switch ic uses a Surface Mount mounting method.As the analog part, the circuit uses an analog IC Multiplexer.As long as the operating temperature is -40°C~85°C, turn signal switch will not be influenced by external factors.Using a 3V~5.5V supply voltage provides digital controlled switch's superior flexibility for designers.Multiplexers from the 74AC series can be used in a wide range of applications.As part of its basic configuration, 20 terminations are designed as a part of it.There is a base part number of 74AC11257 which can also be used in order to locate the logic switch that are related to this item.In this case, 5V is the voltage supplied to the multiplexer's system.In this turn signal switch, there are 20 components that can be connected to each pin.As the end of conductors, it uses GULL WING.This supply type employs Dual.Currently, it is configured with 20 pins.The multiplexer ic is mounted in the direction of Surface Mount.Among the family of AC the logic switch is a member.As a result, signal multiplexer provides 2 bits.Vsup should be kept at 3V to prevent some unnecessary failures.The turn signal switch operates with 1 outputs.It is possible to achieve reliable performance of the multiplexers with a voltage supply of 5V.In this multiplexer, there is a total of 8 inputs.This turn signal switch's circuit uses 4 transmission channels.In addition, CENTER VCC/GND PINS exhibits improved characteristics.
