74HCT257DB,118 Overview
In order to conserve board space, digital switch is included in the 16-SSOP (0.209, 5.30mm Width).In this case, it is packaged as Tape & Reel (TR).The method digital switch ic adopts for mounting is Surface Mount.the multiplexers uses IC Multiplexer as the analog IC.By maintaining the operating temperature at -40°C~125°C, turn signal switch will not be affected by external factors.Design engineers have more flexibility when digital controlled switch operates at 4.5V~5.5V voltage.Multiplexers from the 74HCT series can be used in a wide range of applications.It is designed with 16 terminations as part of its basic configuration.Its logic switch base part number is 74HCT257 which can also be used to find its logic switch related parts.The multiplexer's system is powered by 5V voltage.This turn signal switch has 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 type of supply Single that is employed in this case.There are 16 pins on it.This unit is mounted in the way of Surface Mount.The logic switch is a member of the family of HCT.If the supply voltage is 5V, reliable performance of the multiplexers can be achieved.For the purpose of accepting voltage levels, the multiplexers have 8 input lines.Signal source consists of 4 output lines.
