74ACT11257N Overview
Due to the fact that it is provided in the 20-DIP (0.300, 7.62mm), digital switch allows the board to be compacted.It is packaged according to the Tube method.In terms of mounting, digital switch ic uses the Through Hole method .In the multiplexers, the analog IC is indicated by Multiplexer.In the case of -40°C~85°C, turn signal switch will not be affected by external factors.Using a 4.5V~5.5V supply voltage provides digital controlled switch's superior flexibility for designers.These multiplexers are members of the 74ACT series, which provide extensive application potential.It is designed with 20 terminations as part of its basic configuration.The voltage supplied for multiplexer's system is 5V.multiplexer's systemA component pin count of 20 is found on this turn signal switch.The logic switch belongs to the family of ACT.In order to prevent unnecessary failures, it is recommended that the minimal supply voltage (Vsup) be kept at 4.5V.In order to avoid unnecessary failures, the maximum supply voltage (Vsup) should be kept at 5.5V.The turn signal switch contains 1 outputs designed to operate.This multiplexer has 2 inputs.In addition, CENTER VCC/GND PINS exhibits improved characteristics.
