Working Principles

The 74LVX112M is a dual J-K flip-flop with individual clear inputs. It operates using high-speed CMOS technology, allowing for fast data processing. The flip-flop has two clock inputs, CLK1 and CLK2, which trigger the state change of the outputs Q1 and Q2 based on the input signals J1, K1, J2, and K2. The clear inputs CLR1 and CLR2 reset the flip-flops to a known state when activated.
