DM74AS157N Overview
Due to the lack of space on the board, digital switch is provided in the 16-DIP (0.300, 7.62mm).Tube is the packaging method.Through Hole is the mounting method digital switch ic uses.The analog IC in the multiplexers is identified as Multiplexer.If the operating temperature is maintained at 0°C~70°C, turn signal switch will not be susceptible to external factors.It provides digital controlled switch's superior flexibility for designers to use when it operates with a supply voltage of 4.5V~5.5V.provides digital controlled switch's digital controlled switch'sThe multiplexers from 74AS series can be used for a wide range of applications.The base part number is 74AS157, which can also be used to find its logic switch related parts.The supply type of this multiplexer ic is Single.Currently, it is configured with 16 pins.It is mounted in the way of Through Hole.There are 4 bits in signal multiplexer.The turn signal switch contains 4 outputs designed to operate.Despite not interacting with external factors, it consumes 17.5mA current of multiplexer ic.Providing a supply voltage of 5V can provide reliable performance of the multiplexers.This multiplexer provides 8 inputs.A voltage level can be inserted into the 1 input lines of multiplexers.The signal source consists of 2 output lines.In this case, operating this signal switch at 70°C is acceptable.Temperatures of the multiplexer should be kept at 0°C.Based on the device specifications, the signal switches is designed to operate at 5.5V maximum supply voltage.In compliance with the applicable device specification, the digital swith operates at a minimum supply voltage of 4.5V.During normal operation, the digitalswitch consists of 4 circuits.
