The 74HCT688D from NXP is a high-speed Si-gate CMOS device that functions as an 8-bit magnitude comparator. It is capable of comparing two 8-bit binary or BCD words, with its output indicating when P equals Q.
This component features a typical propagation delay of 7ns from input to output (P=Q) and 8ns when triggered by the enable input. It has a typical input capacitance of 3.5pF and a power dissipation capacitance of 30pF per package. The device is specified in compliance with JEDEC standard no. 7A and is pin-compatible with low-power Schottky TTL (LSTTL).
Designed for general-purpose digital logic applications, the 74HCT688D is suitable for systems requiring binary or BCD word comparison. Its MSI (Medium Scale Integration) category indicates a moderate level of complexity. The device is typically supplied in a DIP package.
