FEATURE
• Industrial temperature range available (–40°C to +85°C)
DESCRIPTION
The 74F112, Dual Negative Edge-Triggered JK-Type Flip-Flop, feature individual J, K, Clock (CPn), Set (SD) and Reset (RD) inputs, true (Qn) and complementary (Qn) outputs. The SD and RD inputs, when Low, set or reset the outputs as shown in the Function Table, regardless of the level at the other inputs. A High level on the clock (CPn) input enables the J and K inputs and data will be accepted. The logic levels at the J and K inputs may be allowed to change while the CPn is High and flip-flop will perform according to the Function Table as long as minimum setup and hold times are observed. Output changes are initiated by the High-to-Low transition of the CPn. TYPE 74F112 TYPICAL PROPAGATION DELAY 100MHz
