SN74HC251DR Overview


Due to the fact that it is provided in the 16-SOIC (0.154, 3.90mm Width), digital switch allows the board to be compacted.It is packaged in the way of Cut Tape (CT).Digital switch ic adheres to a mounting method of Surface Mount.The analog IC used in the multiplexers can be referred to as Multiplexer.By maintaining the operating temperature at -40°C~85°C, turn signal switch will not be affected by external factors.Design engineers have more flexibility when digital controlled switch operates at 2V~6V voltage.The multiplexers can be used for a wide range of applications since they are members of 74HC series.It is designed with 16 terminations as part of its basic configuration.Its logic switch base part number is 74HC251 which can also be used to find its logic switch related parts.The turn signal switch is supplied with a voltage of 5V volts.A component pin count of 16 can be found on this turn signal switch.Using the point GULL WING as an end point of conductors, it is used to determine the terminus of a conductor.In this case, Single is employed as the supply type.There are 16 pins on it.It is mounted in the way of Surface Mount.There is a family of HC/UH members.As a result, signal multiplexer provides 8 bits.To prevent unnecessary failures, it is recommended that the minimum supply voltage (Vsup) remain at 2V.It is advisable to keep the maximum supply voltage (Vsup) at 6V so as to avoid some unnecessary failures.During mux switch's normal operation, 2/6V is provided with a power supply.The turn signal switch operates with 1 outputs.With a supply voltage of 5V, reliable performance of the multiplexers can be achieved.In this multiplexer, there is a total of 8 inputs.The switches package is packaged in accordance with the TR method.For the normal operation of the device, 1 circuits must be formed.
