Purchasing and Inquiry
SN74AS257DR Overview
Due to the lack of space on the board, digital switch is provided in the 16-SOIC (0.154, 3.90mm Width).It is packaged according to the Tape & Reel (TR) method.The mounting method digital switch ic uses is Surface Mount.In the multiplexers, the analog IC Multiplexer is used.By maintaining the operating temperature at 0°C~70°C, turn signal switch will not be affected by external factors.The turn signal switch is designed for use with a 4.5V~5.5V supply voltage, which gives it a lot of flexibility.Multiplexers of the 74AS series can be used in a wide range of applications.It is designed with 16 terminations as part of its basic configuration.For multiplexer's system, 5V voltage is supplied.Using the point GULL WING as an end point of conductors, it is used to determine the terminus of a conductor.Among the family of AS the logic switch is a member.In order to prevent unnecessary failures, it is recommended that the minimal supply voltage (Vsup) be kept at 4.5V.The maximal supply voltage (Vsup) should be kept at 5.5V to avoid some unnecessary failures.The turn signal switch contains 1 outputs designed to operate.This multiplexer is equipped with 2 inputs and 2 outputs.
