74F257ASC Overview
In order to conserve board space, digital switch is included in the 16-SOIC (0.154, 3.90mm Width).The package is packaged in accordance with Tube.Surface Mount is the mounting method digital switch ic uses.In the multiplexers, the analog IC Multiplexer is used.As long as the operating temperature is 0°C~70°C, turn signal switch will not be influenced 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.As a member of 74F series, the multiplexers can be used for a wide range of applications.The basic configuration includes 16 terminations.For multiplexer's system, 5V voltage is supplied.Currently, this turn signal switch has a total of 16 component pins.GULL WING represents the end of conductors.Among the family of F/FAST the logic switch is a member.The minimal supply voltage (Vsup) should be kept at 4.5V to avoid some unnecessary failures.Avoid unnecessary failures by keeping Vsup at 5.5V.The turn signal switch operates with 1 outputs.This multiplexer has 2 inputs.
