The SP8610 and SP8611 are asynchronous ECL divide by four circuits with ECL compatible outputs which can also be used to drive 100Ω lines. They feature input sensitivities of 600mV p-p (800mV p-p above 1300MHz).
The 74HC85 / 74HCT85 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.
The 74HC85 / 74HCT85 are 4-bit magnitude comparators that can be expanded to almost any length. They perform comparison of two 4-bit binary, BCD or other monotonic codes and present the three possible magnitude results at the outputs (QA>B, QA=Band QA
