74ACT11257DWR Overview
In order to save board space, digital switch is located in the 20-SOIC (0.295, 7.50mm Width).The package is packaged in the manner of Tape & Reel (TR).The mounting method digital switch ic uses is Surface Mount.In the multiplexers, the analog IC Multiplexer is used.When the operating temperature is kept at -40°C~85°C, turn signal switch will not be susceptible to external factors.With a supply voltage of 4.5V~5.5V, designers have greater flexibility of digital controlled switch.Several applications are possible for 74ACT series multiplexers.As part of its basic configuration, 20 terminations are designed as a part of it.There is a base part number of 74ACT11257 which can also be used in order to locate the logic switch that are related to this item.In multiplexer's system, 5V is the voltage supplied.This turn signal switch has 20 component pins.Using the point GULL WING as an end point of conductors, it is used to determine the terminus of a conductor.There is a supply type of Dual employed as part of this supply.This multiplexer ic is configured with 20 pins.This unit is mounted in the way of Surface Mount.The logic switch object belongs to the family of ACT.Signal multiplexer provides 2 bits.Avoid unnecessary failures by keeping Vsup at 5.5V.For mux switch's normal operation, power supply 5V is provided.The turn signal switch has 1 outputs.This multiplexer has 8 inputs.In accordance with TR, switches can be packaged.There are a total of 4 channels used for transmitting data in the turn signal switch's circuit.In addition, it provides improved features of CENTER VCC/GND PINS.
