M74HC148B1R Overview
The reason it is provided is that the board space can be saved by placing digital switch in the 16-DIP (0.300, 7.62mm).Tube is the packaging method.The mounting method digital switch ic uses is Through Hole.The analog IC in the multiplexers is identified as Priority Encoder.In the case of -55°C~125°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.With the 74HC series, the multiplexers are suitable for a diverse range of applications.Among its basic configurations are 16 terminations.You can also find related parts by using its logic switch base part number of M74HC148.For multiplexer's system, 4.5V voltage is supplied.In this turn signal switch, there are 16 component pins.Its supply type is Single, which is used as the source of power.The board is configured with 16 pins.As you can see, it is mounted in the direction of Through Hole.In the HC/UH family, the logic switch is included.As a result, signal multiplexer provides 8 bits.Keep Vsup at 2V to avoid unnecessary failures.It is advisable to keep the maximum supply voltage (Vsup) at 6V so as to avoid some unnecessary failures.There is a power supply provided for the mux switch's normal operation of 2/6V.I would classify the digital switch ic as an electronic part belonging to the Arithmetic Circuits category.It is possible to accept voltage levels through 8 input lines of multiplexers.A signal source is provided by 3 output lines.
