SN74HC251PWT Overview
In order to save board space, digital switch is located in the 16-TSSOP (0.173, 4.40mm Width).In this case, it is packaged as Tape & Reel (TR).In terms of mounting, digital switch ic uses the Surface Mount method .As the analog part, the circuit uses an analog IC Multiplexer.In the case of -40°C~85°C, turn signal switch will not be affected by external factors.When digital controlled switch operates at 2V~6V, designers have superior flexibility.These multiplexers are members of the 74HC series, which provide extensive application potential.As part of its basic configuration, 16 terminations are designed as a part of it.There is a base part number 74HC251 that can be used to locate signal switch's related components as well.For multiplexer's system, 5V voltage is supplied.A component pin count of 16 can be found on this turn signal switch.At the end of a conductor, it uses GULL WING as the point where the conductor ends.There is a type of supply Single that is employed in this case.There are 16 pins on it.Surface Mount is the way it is mounted.Among the family of HC/UH the logic switch is a member.Signal multiplexer provides 8 bits.Avoid unnecessary failures by keeping the supply voltage (Vsup) at 2V.It is advisable to keep the maximum supply voltage (Vsup) at 6V in order to prevent some unnecessary failures.For mux switch's normal operation, power supply 2/6V is provided.This turn signal switch has 1 outputs designed for its operation.This multiplexer has 8 inputs.The switches is packaged according to the way of TR.
