DM74AS257N Overview


In order to conserve board space, digital switch is included in the 16-DIP (0.300, 7.62mm).The package is packaged in accordance with Tube.The method digital switch ic adopts for mounting is Through Hole.In the multiplexers, the analog IC Multiplexer is used.Turn signal switch will not be susceptible to the external factors when the operating temperature is kept at 0°C~70°C.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 74AS series, these multiplexers have a wide range of applications.To find signal switch's related components, a base part number of 74AS257 may also be used.Single is employed as its supply type.The board is configured with 16 pins.Multiplexer ics are mounted in the direction of Through Hole.In this signal multiplexer, there are 4 bits that are provided.This turn signal switch has 4 outputs designed for its operation.Despite not interacting with external factors, it consumes 19.7mA current of multiplexer ic.Using a supply voltage of 5V can result in reliable performance of the multiplexers.This multiplexer has a total of 8 inputs.It is possible to accept voltage levels by using one of the 1 input lines of multiplexers.There are 2 output lines designed to serve as the source of the signal.70°C is an acceptable maximum temperature for this signal switch.In order to maintain a minimal operating temperature of the multiplexer, it should be set at 0°C.Upon compliance with the applicable device specifications, the device will operate at the maximum supply voltage of 5.5V.According to its specifications, the digital swith requires a minimum supply voltage of 4.5V.For the normal operation of the device, 4 circuits must be formed.
