SN74LS85N Description

Short technical summary and product information.

The SN74LS85N is a 4-bit magnitude comparator IC manufactured by Texas Instruments. This device performs comparisons of straight binary and straight BCD (8-4-2-1) codes, providing three fully decoded decisions about two 4-bit words (A, B) at its outputs: A>B, A<B, and A=B. It is designed for through-hole mounting and operates within a temperature range of 0°C to 70°C.

With a supply voltage range of 4.75V to 5.25V, the SN74LS85N offers a maximum propagation delay of 45ns at 5V and 15pF. The device is expandable to any number of bits without external gates by cascading multiple units. The cascading paths are implemented with a two-gate-level delay to reduce overall comparison times for longer words. The package type is 16-PDIP, with a standard package quantity of 25 units in a tube.

These comparators are suitable for applications requiring binary code comparison and decision making. The expandable nature allows for flexible implementation in systems requiring comparison of words longer than 4 bits. The active high outputs provide clear indication of the comparison result.
