74ACT11257NSRG4 Overview
Due to the fact that it is provided in the 20-SOIC (0.209, 5.30mm Width), digital switch allows the board to be compacted.As a result, it is packaged in a way that is referred to as Tape & Reel (TR).For mounting, digital switch ic uses the method Surface Mount.The analog IC in the multiplexers is identified as Multiplexer.By maintaining the operating temperature at -40°C~85°C, turn signal switch will not be affected by external factors.With a supply voltage of 4.5V~5.5V, designers have greater flexibility of digital controlled switch.As a member of 74ACT series, the multiplexers can be used for a wide range of applications.There are 20 terminations included in its basic configuration.The base part number is 74ACT11257, which is also useful when looking up signal switch's related components.For multiplexer's system, a voltage of 5V is supplied.This turn signal switch consists of 20 component pins.It is the end of conductors that is represented by GULL WING.There is a type of supply of Dual.There are 20 pins on it.The mount is in Surface Mount.The logic switch is a member of the family of ACT.The maximal supply voltage (Vsup) should be kept at 5.5V to avoid some unnecessary failures.During mux switch's normal operation, 5V is provided with a power supply.A TAPE AND REEL packaging method is used in the switches.On the multiplexers, 8 input lines are provided for accepting voltage levels.Signal source consists of 4 output lines.In addition, it provides improved features of CENTER VCC/GND PINS.
