74ACT11257DBR Overview
Digital switch is provided in the 20-SSOP (0.209, 5.30mm Width) for the purpose of saving board space.The package is in the form of Cut Tape (CT).In terms of mounting, digital switch ic uses the method of Surface Mount.A digital IC Multiplexer is used as the analog component of the multiplexers.When the operating temperature is kept at -40°C~85°C, the machine will not be sensturn signal switchive to external influences.Designers have greater flexibility using digital controlled switch when it works with 4.5V~5.5V voltage.Multiplexers in the 74ACT series are suitable for a wide range of applications.As parts of its basic configuration, 20 terminations are desgined.There is a base part number 74ACT11257 that can be used to locate signal switch's related components as well.The multiplexer's system is powered by 5V volts.This turn signal switch contains 20 component pins.It employs GULL WING as the point at which conductors come to an end.There is a type of supply Dual that is employed in this case.This multiplexer ic is configured with 20 pins.The mounting point is Surface Mount.The logic switch is included into the family of ACT.In the signal multiplexer, there are 2 bits available.It is advisable to keep the maximum supply voltage (Vsup) at 5.5V so as to avoid some unnecessary failures.During mux switch's normal operation, 5V is provided with a power supply.There are 1 outputs designed for the operation of the turn signal switch.The multiplexer provides 8 inputs.The switches packaging is based on TAPE AND REEL.Furthermore, the characteristics of CENTER VCC/GND PINS have been improved.As a result of the operation of the digitalswitch, 4 circuits are formed.
