74VHCT257AMTR Overview
For the purpose of saving board space, digital switch is included in the 16-SOIC (0.154, 3.90mm Width).It is packaged according to the Tape & Reel (TR) method.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.By maintaining the operating temperature at -55°C~125°C, turn signal switch will not be affected by external factors.Designers have greater flexibility when digital controlled switch operates at a 4.5V~5.5V supply voltage.Multiplexers of the 74VHCT series can be used in a wide range of applications.There is a design for terminating 16 as part of its basic configuration.The base part number is 74VHCT257, so you can find its logic switch related parts using that number.The multiplexer's system is supplied with a voltage of 5V.There are 16 component pins in this turn signal switch.As the end of conductors, it uses GULL WING.Single is employed as its supply type.The board has 16 pins configured.It is mounted in the way of Surface Mount.There is a family of AHCT/VHCT members.Normally, 5V is powered by a battery.As part of the operation of this turn signal switch, there are 1 outputs.If the supply voltage is set to 5V, reliable performance of the multiplexers can be achieved.This multiplexer provides 8 inputs.The switches package is packaged in a way which is consistent with TAPE AND REEL.To ensure that the digitalswitch performs properly, 4 circuits are formed.
