SN74LS181NE4 Overview


This device is supplied in the PDIP package. In order to configure it, it uses 24terminations. 5Vis fully flexible due to its voltage supply. The number of all component pins is 24. As [0], it is packaged. As part of the circuit, there are 24pins that connect other components. The device is mounted in the direction of [0]. In this case, it appears as a member of the LS family. This device contains information in 4bits. Pbfree code may result in yes. The device is manufactured at a temperature grade of COMMERCIAL. The voltage source generates 5Vvoltage. This device operates at 70°C°C for extended periods of time with acceptable electrical stability. This device is designed to operate within a specific temperature range, with the lower limit generally set at 0°C. 5.25Vis the maximum voltage available to the device. The minimum voltage available for the device is as low as 4.75V. It is an electronic component of the Arithmetic Circuits family. A logic IC with the type ARITHMETIC LOGIC UNITis used. During normal operation, it consists of 1circuits. When a high-level voltage is applied to the output, there is -400μA current flowing into it. If a specified low-level voltage is applied to the output terminal, there is 8mA current flowing into it.
