The 74HCT688D is a high-speed Si-gate CMOS device from NXP Semiconductors, functioning as an 8-bit magnitude comparator. It is pin-compatible with low-power Schottky TTL (LSTTL) and specified in compliance with JEDEC standard no. 7A.
This comparator performs the comparison of two 8-bit binary or BCD words, with its output indicating when P equals Q. Key electrical characteristics include a typical propagation delay of 7 ns for Pn, Qn to P=Q and 12 ns for the enable input. It has a typical input capacitance of 3.5 pF and a power dissipation capacitance of 30 pF.
The device is suitable for applications requiring binary or BCD word comparison. Its standard output capability and MSI ICC category make it a versatile component in digital logic designs.
