74VHC257TTR Overview
Due to the lack of space on the board, digital switch is provided in the 16-TSSOP (0.173, 4.40mm Width).It is packaged in the way of Tape & Reel (TR).In terms of mounting, digital switch ic uses the Surface Mount method .The multiplexers uses an analog IC Multiplexer as the analog part of the circuit.When the operating temperature is kept at -55°C~125°C, turn signal switch will not be susceptible to external factors.A supply voltage of 2V~5.5V provides digital controlled switch's superior flexibility for designers.Multiplexers from the 74VHC series can be used in a wide range of applications.Among its basic features are 16 terminations.There is a base part number of 74VHC257 which can also be used in order to locate the logic switch that are related to this item.The multiplexer's system is powered by 3.3V volts.There are 16 component pins in this turn signal switch.It is the end of conductors that is represented by GULL WING.There is a type of supply Single that is employed in this case.With 16 pins, it is configured.Multiplexer ics are mounted in the direction of Surface Mount.There is a family of AHC/VHC members.Vsup should be kept at 2V to prevent some unnecessary failures.It is advisable to keep the maximum supply voltage (Vsup) at 5.5V so as to avoid some unnecessary failures.In order for 2/5.5V to operate normally, a power supply is provided.The switches package is packaged in a way which is consistent with TAPE AND REEL.A signal source consists of 1 output lines.To ensure that the digitalswitch performs properly, 4 circuits are formed.
