The DM54LS112J/883B consists of two independent J-K flip-flops. Data at the J and K inputs is transferred to the Q output on the negative-going transition of the clock pulse. The preset and clear inputs allow for asynchronous setting and clearing of the flip-flops, overriding the clock and data inputs. The low power Schottky technology minimizes power consumption while maintaining good speed characteristics. The device operates from a standard 5V power supply. The ceramic package provides excellent hermeticity and resistance to environmental stresses. This device is ideal for applications demanding high reliability and performance, such as aerospace and military systems.
