SN74HC251DE4 Overview
In order to conserve board space, digital switch is included in the 16-SOIC (0.154, 3.90mm Width).As a result, it is packaged in the way of Tube.digital switch ic uses the method of Surface Mount for mounting.As the analog part, the circuit uses an analog IC Multiplexer.As long as the operating temperature is -40°C~85°C, turn signal switch will not be influenced by external factors.Using a 2V~6V supply voltage provides digital controlled switch's superior flexibility for designers.The multiplexers from 74HC series can be used for a wide range of applications.It is designed with 16 terminations as part of its basic configuration.The part number for 74HC251 can be used to find its logic switch related parts as well.For multiplexer's system, 5V voltage is supplied.Currently, this turn signal switch has a total of 16 component pins.As the end of conductors, it uses GULL WING.As a type of supply, Single is employed.The board is configured with 16 pins.The mounting point is Surface Mount.There is a family of HC/UH members.Signal multiplexer consists of 8 bits.To avoid unnecessary failures, keep the supply voltage at 2V (Vsup).To avoid some unnecessary failures, the maximum supply voltage (Vsup) should be kept at 6V.It is provided that 2/6V has a power supply in order to function normally.As part of the operation of this turn signal switch, there are 1 outputs.The performance of the multiplexers can be reliably maintained at a voltage of 5V.The multiplexer provides 8 inputs.
