M74HC157B1R Overview
As a means of saving space, digital switch is provided in the 16-DIP (0.300, 7.62mm).As a result, it is packaged in a way that is referred to as Tube.In terms of mounting, digital switch ic uses the method of Through Hole.The multiplexers uses an analog IC Multiplexer as the analog part of the circuit.As long as the operating temperature is -55°C~125°C, turn signal switch will not be influenced by external factors.Designers have greater flexibility using digital controlled switch when it works with 2V~6V voltage.The multiplexers from 74HC series can be used for a wide range of applications.As part of its basic configuration, 16 terminations are designed as a part of it.The part number for M74HC157 can be used to find its logic switch related parts as well.The turn signal switch is supplied with a voltage of 4.5V volts.A component pin count of 16 can be found on this turn signal switch.Its supply type is Single, which is used as the source of power.A total of 16 pins are configured on this board.Through Hole is the way it is mounted.The logic switch is a member of the HC/UH family.Vsup should be kept at 2V to prevent some unnecessary failures.In order to avoid unnecessary failures, the maximum supply voltage (Vsup) should be kept at 6V.There is a power supply provided for the mux switch's normal operation of 2/6V.The turn signal switch has 1 outputs.This multiplexer provides 8 inputs.A resistance of 125Ohm is used to operate it.This turn signal switch's circuit uses 4 transmission channels.
