74AHC257D,118 Overview


Providing this information in the 16-SOIC (0.154, 3.90mm Width) enables digital switch board space to be saved.As a result, it is packaged in a way that is referred to as Tape & Reel (TR).The mounting method digital switch ic uses is Surface Mount.In the multiplexers, the analog IC is indicated by Multiplexer.The operating temperature will not be affected by external factors when turn signal switch is set to -40°C~125°C.It provides digital controlled switch's superior flexibility for designers to use when it operates with a supply voltage of 2V~5.5V.provides digital controlled switch's digital controlled switch'sThese multiplexers are members of the 74AHC series, which provide extensive application potential.As part of its basic configuration, 16 terminations are designed as a part of it.The base part number is 74AHC257, which can also be used to find its logic switch related parts.For multiplexer's system, a voltage of 5V is supplied.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.There is a supply type of Single employed as part of this supply.The board has 16 pins configured.The multiplexer ic is mounted in the direction of Surface Mount.The logic switch is a member of the family of AHC/VHC/H/U/V.Avoid unnecessary failures by keeping the supply voltage (Vsup) at 2V.Using a supply voltage of 5V can result in reliable performance of the multiplexers.For the purpose of accepting voltage levels, the multiplexers have 8 input lines.As a signal source, there are 4 output lines.
