SN74AHC157DR Overview


In order to save board space, digital switch is located in the 16-SOIC (0.154, 3.90mm Width).As a result, it is packaged in a way that is referred to as Cut Tape (CT).Digital switch ic uses a Surface Mount mounting method.In the multiplexers, the analog IC Multiplexer is used.The operating temperature of -40°C~125°C will not be susceptible to external factors.When operated with a 2V~5.5V supply voltage, digital controlled switch provides digital controlled switch's superior flexibility for designers.These multiplexers are members of the 74AHC series, which provide extensive application potential.There are 16 terminations included in its basic configuration.There is a base part number of 74AHC157 which can also be used in order to locate the logic switch that are related to this item.For multiplexer's system, 3.3V voltage is supplied.This turn signal switch consists of 16 component pins.Using the point GULL WING as an end point of conductors, it is used to determine the terminus of a conductor.As a type of supply, Single is employed.The board is configured with 16 pins.The mount is in Surface Mount.The logic switch belongs to the family of AHC/VHC/H/U/V.In this signal multiplexer, there are 2 bits provided.Avoid unnecessary failures by keeping the supply voltage (Vsup) at 2V.It is advisable that the maximal supply voltage (Vsup) remains at 5.5V to avoid some unnecessary failures.As a result, the turn signal switch consists of 1 outputs.There are 8 inputs provided in this multiplexer.Currently, the switches is packaged in accordance with the TR method.The turn signal switch's circuit consists of 4 channels that are being used for transmission in the circuit.
