74LS85 DIP 4-Bit Magnitude Comparator IC (16-Pin TTL Logic IC)

The 74LS85 DIP 4-Bit Magnitude Comparator IC is a TTL logic integrated circuit that compares two 4-bit binary numbers and determines their relative magnitude. Housed in a 16-pin Dual Inline Package (DIP), it is built using Low Power Schottky (LS) TTL technology, providing high-speed comparison, low power consumption, and reliable digital performance.

The IC provides three comparison outputs indicating whether Input A is greater than Input B (A>B), Input A is equal to Input B (A=B), or Input A is less than Input B (A<B). It also features cascade inputs and outputs, allowing multiple 74LS85 devices to be connected for comparing larger binary numbers in arithmetic and digital control systems.
