SN74HC257PWT Overview
This is a relatively small item of digital switch that is included in the 16-TSSOP (0.173, 4.40mm Width) in order to save space on the board.It is packaged according to the Tape & Reel (TR) method.The mounting method digital switch ic uses is Surface Mount.The analog IC used in the multiplexers can be referred to as Multiplexer.The operating temperature will not be affected by external factors when turn signal switch is set to -40°C~85°C.When digital controlled switch operates at 2V~6V, designers are provided with a greater degree of flexibility.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 74HC257, which can also be used to find its logic switch related parts.The voltage supplied for multiplexer's system is 5V.multiplexer's systemThis turn signal switch has a total 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.There is a supply type of Single employed as part of this supply.Currently, it is configured with a 16 pin configuration.The mounting point is Surface Mount.The logic switch belongs to the family of HC/UH.Signal multiplexer contains 2 bits.Keep Vsup at 2V to avoid unnecessary failures.It is advisable to keep the maximum supply voltage (Vsup) at 6V so as to avoid some unnecessary failures.The turn signal switch has 1 outputs.The switches package is packaged in accordance with TAPE AND REEL.In the turn signal switch's circuit, there are 4 channels used for transmission.
