MC74ACT257MEL Overview
In order to conserve board space, digital switch is included in the 16-SOIC (0.209, 5.30mm Width).As a result, it is packaged in a way that is referred to as Tape & Reel (TR).digital switch ic uses the method of Surface Mount for mounting.As the analog part, the circuit uses an analog IC Multiplexer.If the operating temperature is maintained at -40°C~85°C, turn signal switch will not be susceptible to external factors.It provides digital controlled switch's superior flexibility for designers to use when it operates with a supply voltage of 4.5V~5.5V.provides digital controlled switch's digital controlled switch'sMultiplexers from the 74ACT series can be used in a wide range of applications.There are 16 terminations included in its basic configuration.You can also find related parts by using its logic switch base part number of 74ACT257.The turn signal switch is supplied with a voltage of 5V volts.This turn signal switch consists of 16 component pins.Using the point GULL WING as an end point of conductors, it is used to determine the terminus of a conductor.This supply type employs Single.The board has 16 pins configured.Multiplexer ics are mounted in the direction of Surface Mount.The logic switch object belongs to the family of ACT.Signal multiplexer contains 4 bits.Vsup (maximum supply voltage) should be kept as 5.5V to prevent unnecessary failures.It is provided that 5V has a power supply in order to function normally.The switches is packaged according to the way of TAPE AND REEL.Voltage levels are accepted through 2 input lines of multiplexers.A signal source is provided by 3 output lines.
