The SNJ54LS85W is an Integrated Circuit (IC) component that belongs to the 54LS series of TTL (Transistor-Transistor Logic) devices. This particular IC is a 4-bit magnitude comparator, which means it is designed to compare two 4-bit binary numbers and determine their relationship, such as equality, greater than, or less than.
Key features of the SNJ54LS85W include:
1. 4-bit Comparisons: It can compare two 4-bit numbers, each consisting of four individual bits (A3, A2, A1, A0) and (B3, B2, B1, B0).
2. Magnitude Detection: The magnitude of the two input numbers can be determined by the digital outputs, namely EQ (equality), G (greater than), and L (less than).
3. Multiple Inputs: The SNJ54LS85W has two sets of inputs for the numbers to be compared. These inputs are labeled as A and B.
4. Active Low Outputs: The outputs of SNJ54LS85W are active low, meaning that they are normally high (logic level 1) and become low (logic level 0) only when the corresponding condition is met.
5. Cascadable: This IC can be cascaded to compare larger numbers by connecting the outputs of one device to the inputs of another
