SN74LS181NE4 Product Details

SN74LS181NE4 Overview


This device is supplied in the PDIP package. It is configured using 24terminations. Having a supply voltage of 5V enables to operate in a fully flexible manner. In total, there are 24pins on the component. In this case, it is packaged as Rail/Tube. Circuit components are connected by 24pins. It is mounted using the way of [0]. Initially, it appears to belong to the LS family. There is information in the device in the form of 4bits. As far as Pbfree code is concerned, the result may be yes. Temperature grade COMMERCIALhas been selected for this device. As a result of the voltage source, there is 5V voltage. Long-term operation at 70°Cwith acceptable electrical stability is possible. It operates over a specified temperature range with a lower limit generally set to 0°C. The maximum voltage that can be applied to the device is 5.25V. It is possible to operate the device at as low a voltage as 4.75V. It is part of the Arithmetic Circuitsfamily of electronic components. It uses the logic IC type [0]. During normal operation, it consists of 1circuits. When a high-level voltage is applied to the output, there is -400μA current flowing into it. When a low-level voltage is specified, there is 8mA current flowing into the output terminal.
