SN74LS251DR Overview


In order to conserve board space, digital switch is included in the 16-SOIC (0.154, 3.90mm Width).It is packaged according to the Tape & Reel (TR) method.The method digital switch ic adopts for mounting is Surface Mount.Multiplexer is the analog IC that the multiplexers uses.If the operating temperature is maintained at 0°C~70°C, turn signal switch will not be susceptible to external factors.Using a 4.75V~5.25V supply voltage provides digital controlled switch's superior flexibility for designers.Multiplexers from the 74LS series can be used in a wide range of applications.This configuration includes 16 terminations as part of its basic functionality.To find signal switch's related components, a base part number of 74LS251 may also be used.The multiplexer is supplied with 5V voltage.Signal switch has 16 component pins.As a result, conductors end at GULL WING.The supply type of this multiplexer ic is Single.Currently, it is configured with 16 pins.This unit is mounted in the way of Surface Mount.The logic switch belongs to the family of LS.Signal multiplexer contains 8 bits.The power supply of 5V is provided for mux switch's normal operation.As part of the operation of this turn signal switch, there are 1 outputs.In the absence of external influences, it consumes 7.1mA current of multiplexer ic.Using a supply voltage of 5V can result in reliable performance of the multiplexers.This multiplexer has a total of 8 inputs.The signal switching is packaged by TR. It is necessary for the digitalswitch to operate normally that 1 circuits be formed.
