74AC257TTR Overview
Digital switch is provided in the 16-TSSOP (0.173, 4.40mm Width) for the purpose of saving board space.It is packaged in the way of Tape & Reel (TR).In terms of mounting, digital switch ic uses the Surface Mount method .In the multiplexers, the analog IC Multiplexer is used.When the operating temperature is kept at -55°C~125°C, turn signal switch will not be susceptible to external factors.When digital controlled switch operates at 2V~6V, designers are provided with a greater degree of flexibility.Multiplexers in the 74AC series are suitable for a wide range of applications.The part number for 74AC257 can be used to find its logic switch related parts as well.As a type of supply, Single is employed.With 16 pins, it is configured.The mounting point is Surface Mount.This multiplexer has 8 inputs.To operate the digitalswitch normally, 4 circuits are formed.
