74ACT257PC Overview
Due to the fact that it is provided in the 16-DIP (0.300, 7.62mm), digital switch allows the board to be compacted.It is packaged in the way of Tube.Digital switch ic uses a Through Hole mounting method.In the multiplexers, the analog IC is indicated by Multiplexer.When the operating temperature is kept at -40°C~85°C, the machine will not be sensturn signal switchive to external influences.When digital controlled switch operates at 4.5V~5.5V, designers are provided with a greater degree of flexibility.These multiplexers are members of the 74ACT series, which provide extensive application potential.To find signal switch's related components, a base part number of 74ACT257 may also be used.The supply type of this multiplexer ic is Single.A configuration of 16 pins is used.The mounting is in the way of Through Hole.Signal multiplexer consists of 4 bits.There are 4 outputs designed to operate the turn signal switch.When a supply voltage of 5V is used, reliable performance of the multiplexers can be achieved.This multiplexer provides 8 inputs.As a voltage level input, the multiplexers have 2 lines.As a signal source, there are 3 output lines.85°C is an acceptable maximum temperature for this signal switch.Temperatures of the multiplexer should be kept at -40°C.The device is specified to operate at the maximum supply voltage of 5.5V in accordance with its applicable specification.The digital swith is specified to operate at the minimum supply voltage of 4.5V in compliance with the applicable device specification.The digitalswitch relies on 4 circuits to function normally.
