SN74HCT257DRE4 Overview
Due to the lack of space on the board, digital switch is provided in the 16-SOIC (0.154, 3.90mm Width).It is packaged according to the Tape & Reel (TR) method.Surface Mount is the mounting method digital switch ic uses.As the analog part, the circuit uses an analog IC Multiplexer.In the case of -40°C~85°C, turn signal switch will not be affected by external factors.When operated with a 4.5V~5.5V supply voltage, digital controlled switch provides digital controlled switch's superior flexibility for designers.Several applications are possible for 74HCT series multiplexers.There are 16 terminations included in its basic configuration.The base part number is 74HCT257, which is also useful when looking up signal switch's related components.The voltage supplied for multiplexer's system is 5V.multiplexer's systemThis turn signal switch consists of 16 component pins.As a result, GULL WING represents the end of the conductors.This supply type employs Single.It is configured with 16 pins.This unit is mounted in the way of Surface Mount.In the HCT family, the logic switch is included.In the signal multiplexer, there are 2 bits available.The power supply of 5V is provided for mux switch's normal operation.The turn signal switch has 1 outputs.The performance of the multiplexers of a system can be reliably achieved with a supply voltage of 5V.This multiplexer is equipped with 8 inputs and 8 outputs.A TR packaging method is used in the switches.A total of 4 transmission channels are available in the turn signal switch's circuit.
