SN74S85N Description

Short technical summary and product information.

The SN74S85N 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 (A>B, A<B, A=B) at its outputs.

 

Key electrical specifications include an operating voltage range of 4.75V to 5.25V and a maximum propagation delay of 18ns at 5V with a 15pF load capacitance. It supports output currents of 1mA and 20mA.

 

The SN74S85N is designed for through-hole mounting and comes in a 16-PDIP package. It is expandable to any number of bits without external gates by cascading multiple units. The operating temperature range is from 0°C to 70°C.

 

This comparator is suitable for digital logic applications requiring binary code comparison. It is RoHS3 Compliant and has an MSL rating of 1.
