MM74HC251M Overview
Due to the lack of space on the board, digital switch is provided in the 16-SOIC (0.154, 3.90mm Width).It is packaged in the way of Tube.Surface Mount is the mounting method digital switch ic uses.the multiplexers uses an analog IC Multiplexer.By keeping the operating temperature at -40°C~85°C, turn signal switch will not be affected by external factors.When digital controlled switch operates at 2V~6V, designers are provided with a greater degree of flexibility.Multiplexers in the 74HC series are suitable for a wide range of applications.As part of its basic configuration, 16 terminations are designed as a part of it.For multiplexer's system, a voltage of 5V is supplied.Signal switch has 16 component pins.Using the point GULL WING as an end point of conductors, it is used to determine the terminus of a conductor.In the HC/UH family, the logic switch is included.Keep Vsup at 2V to avoid unnecessary failures.It is advisable to keep the maximum supply voltage (Vsup) at 6V in order to prevent some unnecessary failures.As a result, the turn signal switch consists of 1 outputs.In this multiplexer, there is a total of 8 inputs.
