74ACT11257N Overview
In order to conserve board space, digital switch is included in the 20-DIP (0.300, 7.62mm).The package is in the form of Tube.Digital switch ic adheres to a mounting method of Through Hole.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.The turn signal switch is designed for use with a 4.5V~5.5V supply voltage, which gives it a lot of flexibility.In addition to being a member of the 74ACT series, these multiplexers have a wide range of applications.Its basic configuration includes terminations in the 20 range.In addition, it also has a base part number of 74ACT11257, which can be used to find related parts.The voltage supplied for multiplexer's system is 5V.multiplexer's systemThis turn signal switch has a total of 20 component pins.There is a type of supply of Dual.A total of 20 pins are configured on this board.The mounting is in the way of Through Hole.There is a family of ACT members.There are 4 bits in signal multiplexer.In order to avoid unnecessary failures, the maximum supply voltage (Vsup) should be kept at 5.5V.There is a power supply provided for the mux switch's normal operation of 5V.For the turn signal switch's operation, there are 1 outputs.In order to accept voltage levels, the multiplexers have input lines 2 on the board.Also, it provides an improved version of the characteristics of CENTER VCC/GND PINS.
