SN74AS138DR Overview
Due to the lack of space on the board, digital switch is provided in the 16-SOIC (0.154, 3.90mm Width).The package is packaged in the manner of Tape & Reel (TR).digital switch ic uses the method of Surface Mount for mounting.In the multiplexers, the analog IC is indicated by Decoder/Demultiplexer.Turn signal switch will not be susceptible to the external factors when the operating temperature is kept at 0°C~70°C.With a supply voltage of 4.5V~5.5V, designers have greater flexibility of digital controlled switch.As a member of 74AS series, the multiplexers can be used for a wide range of applications.As part of its basic configuration, 16 terminations are designed as a part of it.There is a base part number 74AS138 that can be used to locate signal switch's related components as well.For multiplexer's system, 5V voltage is supplied.Currently, this turn signal switch has a total of 16 component pins.It is the end of conductors that is represented by GULL WING.As a type of supply, Single is employed.There are 16 pins on it.The multiplexer ic is mounted in the direction of Surface Mount.I would like to refer to the logic switch as a member of the AS family.There is a power supply provided for the mux switch's normal operation of 5V.Decoder/Drivers is the classification for this the digital switch ic.When a supply voltage of 5V is used, reliable performance of the multiplexers can be achieved.On the multiplexers, 3 input lines are provided for accepting voltage levels.A signal source consists of 8 output lines.
