SN74HC251PWRG4 Overview


Due to the lack of space on the board, digital switch is provided in the 16-TSSOP (0.173, 4.40mm Width).As a result, it is packaged in a way that is referred to 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.Turn signal switch will not be susceptible to the external factors when the operating temperature is kept at -40°C~85°C.Using a 2V~6V supply voltage provides digital controlled switch's superior flexibility for designers.As a member of 74HC series, the multiplexers can be used for a wide range of applications.As parts of its basic configuration, 16 terminations are desgined.The part number for 74HC251 can be used to find its logic switch related parts as well.For multiplexer's system, a voltage of 5V is supplied.This turn signal switch contains 16 component pins.As a result, GULL WING represents the end of the conductors.Its supply type is Single, which is used as the source of power.A configuration of 16 pins is used.The multiplexer ic is mounted in the direction of Surface Mount.Among the family of HC/UH the logic switch is a member.As a result, signal multiplexer provides 8 bits.To prevent unnecessary failures, it is recommended that the minimum supply voltage (Vsup) remain at 2V.Keeping Vsup at 6V will prevent some unnecessary failures.A power supply is provided for mux switch's normal operation of 2/6V.For the turn signal switch's operation, there are 1 outputs.Using a supply voltage of 5V can result in reliable performance of the multiplexers.In this multiplexer, there is a total of 8 inputs.The switches package is packaged in a way which is consistent with TR.
