SN74HC251DBR Overview
This is a relatively small item of digital switch that is included in the 16-SSOP (0.209, 5.30mm Width) in order to save space on the board.Cut Tape (CT) is the packaging method.Mounting is performed using Surface Mount.In the multiplexers, the analog IC Multiplexer is used.As long as the operating temperature is -40°C~85°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.Several applications are possible for 74HC series multiplexers.The basic configuration of this system includes 16 terminations.To find signal switch's related components, a base part number of 74HC251 may also be used.The multiplexer's system is powered by 5V volts.A component pin count of 16 can be found on this turn signal switch.It employs GULL WING as the point at which conductors come to an end.Single is employed as its supply type.With 16 pins, it is configured.Surface Mount is the way it is mounted.The logic switch is a member of the HC/UH family.Signal multiplexer contains 8 bits.The minimal supply voltage (Vsup) should be kept at 2V to avoid some unnecessary failures.It is advisable that the maximal supply voltage (Vsup) remains at 6V to avoid 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.When a supply voltage of 5V is used, reliable performance of the multiplexers can be achieved.There are 8 inputs provided in this multiplexer.A TR packaging method is used in the switches.A normal operation of the digitalswitch requires 1 circuits.
