CD74AC257E Overview
Due to the fact that it is provided in the 16-DIP (0.300, 7.62mm), digital switch allows the board to be compacted.As a result, it is packaged in the way of Tube.Digital switch ic adheres to a mounting method of Through Hole.In the multiplexers, the analog IC is indicated by Multiplexer.By keeping the operating temperature at -55°C~125°C, turn signal switch will not be affected by external factors.When digital controlled switch operates at 1.5V~5.5V, designers are provided with a greater degree of flexibility.Multiplexers in the 74AC series are suitable for a wide range of applications.As part of its basic configuration, 16 terminations are designed as a part of it.The base part number is 74AC257, which is also useful when looking up signal switch's related components.For multiplexer's system, a voltage of 3.3V is supplied.Signal switch has 16 component pins.In this case, the supply type is Single.This multiplexer ic is configured with 16 pins.The mount is in Through Hole.The logic switch is a member of the AC family.Signal multiplexer contains 2 bits.The maximal supply voltage (Vsup) should be kept at 5.5V to avoid some unnecessary failures.A power supply is provided for mux switch's normal operation of 3.3/5V.The turn signal switch operates with 1 outputs.In this multiplexer, there is a total of 8 inputs.This turn signal switch's circuit is based on a circuit with 4 channels.
