M74HC138B1R Overview
This is a relatively small item of digital switch that is included in the 16-DIP (0.300, 7.62mm) in order to save space on the board.The package is in the form of Tube.Mounting is performed using Through Hole.As the analog part, the circuit uses an analog IC Decoder/Demultiplexer.If the operating temperature is maintained at -55°C~125°C, turn signal switch will not be susceptible to external factors.Designers have greater flexibility using digital controlled switch when it works with 2V~6V voltage.Multiplexers in the 74HC series are suitable for a wide range of applications.Among its basic configurations are 16 terminations.In addition, it also has a base part number of M74HC138, which can be used to find related parts.For multiplexer's system, a voltage of 4.5V is supplied.This turn signal switch has a total of 16 component pins.There is a supply type of Single employed as part of this supply.The board is configured with 16 pins.The mount is in Through Hole.There is a family of HC/UH members.It is recommended that the minimum supply voltage (Vsup) be kept at 2V to avoid some unnecessary failures.Vsup (maximum supply voltage) should be kept as 6V to prevent unnecessary failures.For mux switch's normal operation, there is a power supply provided at 2/6V.The turn signal switch operates with 8 outputs.Decoder/Drivers is the classification for this the digital switch ic.Despite not interacting with external factors, it consumes 4μA current of multiplexer ic.This multiplexer provides 3 inputs.It contains 1 elements in mux switch configuration.
