74AC11257N Overview
This is a relatively small item of digital switch that is included in the 20-DIP (0.300, 7.62mm) in order to save space on the board.As a result, it is packaged in a way that is referred to as Tube.Digital switch ic uses a Through Hole mounting method.the multiplexers uses IC Multiplexer as the analog IC.If the operating temperature is maintained at -40°C~85°C, turn signal switch will not be susceptible to external factors.When operated with a 3V~5.5V supply voltage, digital controlled switch provides digital controlled switch's superior flexibility for designers.These multiplexers are members of the 74AC series, which provide extensive application potential.It is designed with 20 terminations as part of its basic configuration.There is a base part number of 74AC11257 which can also be used in order to locate the logic switch that are related to this item.For multiplexer's system, a voltage of 5V is supplied.This turn signal switch consists of 20 component pins.There is a supply type of Dual employed as part of this supply.This multiplexer ic is configured with 20 pins.Through Hole is the way it is mounted.The logic switch is a member of the AC family.The multiplexer ic provides 2 bits.To avoid unnecessary failures, keep the supply voltage at 3V (Vsup).The turn signal switch contains 1 outputs designed to operate.If the supply voltage is set to 5V, reliable performance of the multiplexers can be achieved.This multiplexer provides 8 inputs.This turn signal switch's circuit is based on a circuit with 4 channels.Additionally, it improves the characteristics of CENTER VCC/GND PINS.
