74ACT11257NSR Overview
Due to the fact that it is provided in the 20-SOIC (0.209, 5.30mm Width), digital switch allows the board to be compacted.The package is packaged in the manner of Tape & Reel (TR).Digital switch ic adheres to a mounting method of Surface Mount.In the multiplexers, the analog IC is indicated by Multiplexer.When the operating temperature is kept at -40°C~85°C, the machine will not be sensturn signal switchive to external influences.When operated with a 4.5V~5.5V supply voltage, digital controlled switch provides digital controlled switch's superior flexibility for designers.As a member of 74ACT series, the multiplexers can be used for a wide range of applications.There are 20 terminations included in its basic configuration.In addition, it also has a base part number of 74ACT11257, which can be used to find related parts.The multiplexer's system is supplied with a voltage of 5V.There are 20 component pins in this turn signal switch.Using the point GULL WING as an end point of conductors, it is used to determine the terminus of a conductor.As a type of supply, Dual is employed.It is configured with 20 pins.The multiplexer ic is mounted in the direction of Surface Mount.There is a family of ACT members.The multiplexer ic provides 4 bits.Avoid unnecessary failures by keeping Vsup at 5.5V.It is provided that 5V has a power supply in order to function normally.The turn signal switch has 1 outputs.TAPE AND REEL is used to package the switches.A voltage level can be inserted into the 2 input lines of multiplexers.Furthermore, the characteristics of CENTER VCC/GND PINS have been improved.
