74AC257SCX Overview
The reason it is provided is that the board space can be saved by placing digital switch in the 16-SOIC (0.154, 3.90mm Width).As a result, it is packaged in a way that is referred to as Tape & Reel (TR).digital switch ic uses the method of Surface Mount for mounting.the multiplexers uses an analog IC Multiplexer.Turn signal switch will not be susceptible to the external factors when the operating temperature is kept at -40°C~85°C.Using a 2V~6V supply voltage provides digital controlled switch's superior flexibility for designers.With the 74AC series, the multiplexers are suitable for a diverse range of applications.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.Its supply type is Single, which is used as the source of power.A total of 16 pins are configured on this board.This unit is mounted in the way of Surface Mount.The multiplexer ic provides 4 bits.In order for the turn signal switch to work, there are 4 outputs.The multiplexer is equipped with 8 inputs.As a voltage level input, the multiplexers have 2 lines.There are 3 output lines designed to serve as the source of the signal.Signal switchs at temperatures up to 85°C are acceptable.It is recommended that a minimum operating temperature of the multiplexer of -40°C be maintained.Device specifications specify 6V as the maximum supply voltage for the signal switches.Typical device specifications specify a voltage supply of 2V for the digital swith.
