The 74HC/HCT688 from Philips, specifically the 74HCT688N,652 variant, is a high-speed Si-gate CMOS 8-bit magnitude comparator. It is pin compatible with low power Schottky TTL (LSTTL) and specified in compliance with JEDEC standard no. 7A.
This integrated circuit performs the comparison of two 8-bit binary or BCD words, providing an output indicating P = Q. Key electrical characteristics include a typical propagation delay of 7 ns for Pn, Qn to P=Q and 12 ns for E to P=Q, with a load capacitance of 15 pF at 5V. The input capacitance is typically 3.5 pF, and the power dissipation capacitance per package is 30 pF.
The 74HC/HCT688 is suitable for applications requiring binary or BCD word comparison. Its MSI (Medium Scale Integration) classification and standard output capability make it a versatile component in digital logic designs.
