74AC257SJ Overview
This is a relatively small item of digital switch that is included in the 16-SOIC (0.209, 5.30mm Width) in order to save space on the board.As a result, it is packaged in a way that is referred to as Tube.The method digital switch ic adopts for mounting is Surface Mount.For the analog part of the multiplexers, an IC Multiplexer is used.By keeping the operating temperature at -40°C~85°C, turn signal switch will not be affected by external factors.Designers have greater flexibility using digital controlled switch when it works with 2V~6V voltage.The multiplexers can be used for a wide range of applications since they are members of 74AC series.There is a base part number of 74AC257 which can also be used in order to locate the logic switch that are related to this item.The supply type of this multiplexer ic is Single.This multiplexer ic is configured with 16 pins.The mounting point is Surface Mount.As a result, signal multiplexer provides a total of 4 bits.There are 4 outputs designed to operate the turn signal switch.This multiplexer has a total of 8 inputs.Voltage levels are accepted through 2 input lines of multiplexers.A signal source is provided by 3 output lines.It is acceptable for this signal switch to operate at the maximal temperature of 85°C.Ideally, the temperature of the multiplexer should not exceed -40°C.According to the applicable device specification, the signal switches operates at a maximum supply voltage of 6V.A minimum supply voltage of 2V is specified for the digital swith in accordance with its applicable specifications.
