74VHCT257ATTR Overview
In order to save board space, digital switch is located in the 16-TSSOP (0.173, 4.40mm Width).Tape & Reel (TR) represents its packaging.In terms of mounting, digital switch ic uses the method of Surface Mount.As the analog part, the circuit uses an analog IC Multiplexer.A temperature of -55°C~125°C will not leave the turn signal swturn signal switchch susceptible to external influences.When digital controlled switch operates at 4.5V~5.5V, designers are provided with a greater degree of flexibility.With the 74VHCT series, the multiplexers are suitable for a diverse range of applications.It is designed with 16 terminations as part of its basic configuration.The part number for 74VHCT257 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.It is the end of conductors that is represented by GULL WING.There is a supply type of Single employed as part of this supply.A total of 16 pins are configured on this board.As you can see, it is mounted in the direction of Surface Mount.The logic switch is included into the family of AHCT/VHCT.For mux switch's normal operation, there is a power supply provided at 5V.The turn signal switch contains 1 outputs designed to operate.It is possible to achieve reliable performance of the multiplexers with a voltage supply of 5V.The multiplexer is equipped with 8 inputs.In accordance with TAPE AND REEL, switches can be packaged.As a result of the operation of the digitalswitch, 4 circuits are formed.
