Features  
Description  
• Buffered Inputs and Outputs  
The ’HC85 and ’HCT85 are high speed magnitude  
comparators that use silicon-gate CMOS technology to  
achieve operating speeds similar to LSTTL with the low  
power consumption of standard CMOS integrated circuits.  
• Typical Propagation Delay: 13ns (Data to Output at

• Serial or Parallel Expansion Without External Gating  
These 4-bit devices compare two binary, BCD, or other  
monotonic codes and present the three possible magnitude  
results at the outputs (A > B, A < B, and A = B). The 4-bit  
input words are weighted (A0 to A3 and B0 to B3), where A3

• Balanced Propagation Delay and Transition Times  
The devices are expandable without external gating, in both  
serial and parallel fashion. The upper part of the truth table  
indicates operation using a single device or devices in a  
serially expanded application. The parallel expansion  
scheme is described by the last three entries in the truth  
table.
