The document describes the features and characteristics of Harris Semiconductor SCHS136E, including buffered inputs and outputs, propagation delay, serial or parallel expansion, etc.
The CD54HC85, CD74HC85, CD54HCT85 and CD74HCT85 are high‑speed CMOS 4‑bit magnitude comparators that compare two binary, BCD or other monotonic codes and output A>B, A The devices are offered in a variety of packages (CERDIP, PDIP, SOIC, SOP, TSSOP) with detailed ordering information, mechanical dimensions, and handling cautions. Absolute maximum ratings, DC electrical specifications, and switching performance are listed for both HC and HCT families. The typical propagation delay is 13 ns when Vcc = 5 V, CL = 15 pF and the ambient temperature is 25 °C. They operate from –55 °C up to 125 °C. Available packages include PDIP, SOIC, SOP and TSSOP, with 16‑lead configurations.What's inside
