SN74HC257DRE4 Overview
In order to save board space, digital switch is located in the SOIC.Tape & Reel (TR) is the method used for packaging.The basic configuration includes 16 terminations.For multiplexer's system, a voltage of 5V is supplied.Currently, this turn signal switch has a total of 16 component pins.It employs GULL WING as the point at which conductors come to an end.As a type of supply, Single is employed.This multiplexer ic has 16 pins configured.The mounting is in the way of Surface Mount.In the HC/UH family, the logic switch is included.Reliable performance of the multiplexers can be achieved when a supply voltage of 5V is provided.The multiplexer provides 8 inputs.The signal switching is packaged by TAPE AND REEL. A voltage level can be inserted into the 2 input lines of multiplexers.As a signal source, there are 1 output lines.The turn signal switch's circuit consists of 4 channels that are being used for transmission in the circuit.There is no problem with operating this signal switch at the maximum temperature of 85°C.A temperature of the multiplexer of -40°C should be maintained for minimal operation.According to the applicable device specification, the signal switches operates at a maximum supply voltage of 6V.Typical device specifications specify a voltage supply of 2V for the digital swith.
