                                                XC74WL157ASR Overview
In order to conserve board space, digital switch is included in the 8-TSSOP, 8-MSOP (0.110, 2.80mm Width).Tape & Reel (TR) is the method used for packaging.Mounting is performed using Surface Mount.the multiplexers uses an analog IC Multiplexer.When the operating temperature is kept at -40°C~85°C, turn signal switch will not be susceptible to external factors.When digital controlled switch operates at 2V~5.5V, designers are provided with a greater degree of flexibility.As a member of 74WL series, the multiplexers can be used for a wide range of applications.There are 8 terminations included in its basic configuration.As its base part number is 74WL157, logic switch can also be used to find its related parts.A conductor terminates at GULL WING.There is a type of supply of Single.Multiplexer ics are mounted in the direction of Surface Mount.It is provided that 2/5.5V has a power supply in order to function normally.This multiplexer has a total of 2 inputs.
