SN74HC157DBR Overview


Due to the lack of space on the board, digital switch is provided in the 16-SSOP (0.209, 5.30mm Width).Tape & Reel (TR) is the method used for packaging.The method digital switch ic adopts for mounting is Surface Mount.The multiplexers uses an analog IC Multiplexer as the analog part of the circuit.As long as the operating temperature is -40°C~85°C, turn signal switch will not be influenced by external factors.Design engineers have more flexibility when digital controlled switch operates at 2V~6V voltage.These multiplexers are members of the 74HC series, which provide extensive application potential.As parts of its basic configuration, 16 terminations are desgined.The base part number is 74HC157, which is also useful when looking up signal switch's related components.For multiplexer's system, a voltage of 5V is supplied.This turn signal switch has 16 component pins.GULL WING represents the end of conductors.In this case, Single is employed as the supply type.It is configured with 16 pins.The mount is in Surface Mount.The logic switch is included into the family of HC/UH.Signal multiplexer provides 2 bits.Keeping Vsup at 2V will prevent some unwanted failures.The maximal supply voltage (Vsup) should be kept at 6V to avoid some unnecessary failures.In order for the turn signal switch to work, there are 1 outputs.With a supply voltage of 5V, reliable performance of the multiplexers can be achieved.A multiplexer such as this has 8 inputs available.The switches package is packaged in a way which is consistent with TR.This turn signal switch's circuit is based on a circuit with 4 channels.
