DM74AS157M Overview
For the purpose of saving board space, digital switch is included in the 16-SOIC (0.154, 3.90mm Width).The package is in the form of Tube.Digital switch ic uses a Surface Mount mounting method.The multiplexers uses an analog IC Multiplexer as the analog part of the circuit.Turn signal switch will not be susceptible to the external factors when the operating temperature is kept at 0°C~70°C.When digital controlled switch operates at 4.5V~5.5V, designers have superior flexibility.In addition to being a member of the 74AS series, these multiplexers have a wide range of applications.The part number for 74AS157 can be used to find its logic switch related parts as well.Single is used as its supply type.With 16 pins, it is configured.The multiplexer ic is mounted in the direction of Surface Mount.In this signal multiplexer, there are 4 bits that are provided.As a result, the turn signal switch consists of 4 outputs.Without any external influences, it consumes 17.5mA current of multiplexer ic at all times.If the supply voltage is 5V, reliable performance of the multiplexers can be achieved.The multiplexer is equipped with 8 inputs.It is possible to accept voltage levels by using one of the 1 input lines of multiplexers.As a signal source, there are 2 output lines.The maximum temperature for this signal switch is 70°C.Maintaining a minimum operating temperature of the multiplexer of 0°C is recommended.Upon compliance with the applicable device specifications, the device will operate at the maximum supply voltage of 5.5V.Typical device specifications specify a voltage supply of 4.5V for the digital swith.4 circuits are formed for the normal operation of the digitalswitch.
