Important notice Dear Customer, On 7 February 2017 the former NXP Standard Product business became a new company with the tradename Nexperia. Nexperia is an industry leading supplier of Discrete, Logic and PowerMOS semiconductors with its focus on the automotive, industrial, computing, consumer and wearable application markets In data sheets and application notes which still contain NXP or Philips Semiconductors references, use the references to Nexperia, as shown below. Instead of http://www.nxp.com, http://www.philips.com/ or http://www.semiconductors.philips.com/, use http://www.nexperia.com Instead of sales.addresses@www.nxp.com or sales.addresses@www.semiconductors.philips.com, use salesaddresses@nexperia.com (email) Replace the copyright notice at the bottom of each page or elsewhere in the document, depending on the version, as shown below: - © NXP N.V.

FEATURES • Serial or parallel expansion without extra gating The operation of the “85” is described in the function table, showing all possible logic conditions. The upper part of the table describes the normal operation under all conditions that will occur in a single device or in a series expansion scheme. In the upper part of the table the three outputs are mutually exclusive. In the lower part of the table, the outputs reflect the feed forward conditions that exist in the parallel expansion scheme. • Magnitude comparison of any binary words • Output capability: standard • ICC category: MSI GENERAL DESCRIPTION The 74HC/HCT85 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. For proper compare operation the expander inputs (IA>B, IA=B and IAB, QA=B and QAB, QA B expansion input 5 QA>B A > B output 6 QA=B A = B output 7 QAB IAB QAB3 A3B2 A2B1 A1B0 A0B or QAB or QA
