SN54S181J Product Details

SN54S181J Overview


This device is supplied in the CDIP package. It is configured with 24terminations. Having a voltage supply of 5Vallows it to operate in a highly flexible manner. The 1elements are connected by wires. A total of 24pins are present on all components. Rail/Tubeis used to package it. In the circuit, there are 24pins that connect other components. It is a member of the family [0]. The device contains 4bits of information. There is a temperature grade of MILITARYon this device. For the device to operate, a voltage supply of 5Vis required. Despite operating at 125°Cfor extended periods, its electrical characteristics remain stable. This device is designed to operate within a specified temperature range with a lower limit generally set at -55°C. There is a maximum voltage available for the device of 5.5V. It is possible for the device to operate at a voltage as low as 4.5V. The part is from Arithmetic Circuits family. It uses a logic IC type of [0]. At a high-level voltage specified, there is -1mA current flowing into the output. At a specified low-level voltage, there is 20mA current flowing into the output terminal.
