SN54LS181J Product Details

SN54LS181J Overview


This device is packaged in a CDIP package. The configuration of this device is based on 24terminations. With a supply voltage of 5V volts, it is possible to run it in a fully flexible manner. The device has 1terminations. A total of 24pins are available on all components. In the circuit, there are 24pins that connect other parts. Through Holeis the way in which it is mounted. In this case, it appears as a member of the LS family. There are 4bits of information contained in the device. The device is manufactured at MILITARYdegrees Celsius. It is packed using [0]. The voltage source produces a voltage of 5V volts. In order to operate, it requires a voltage of [0]. Electrical characteristics are acceptable at extended periods of time at temperatures above [0]. Generally, the temperature limit is set at -55°Cso it will operate over a specified range. 5.5Vis the maximum voltage the device can handle. It is possible to supply the device with a voltage as low as 4.5V. This electronic component is from the Arithmetic Circuits family. In this case, ARITHMETIC LOGIC UNITrefers to the logic IC type being used. The output has -400μAcurrent when a high voltage is applied. Initially, there is4mA current flowing into the output terminal at the specified voltage level.
