The SN74LS112ANSR is a high-performance, dual negative-edge-triggered master-slave flip-flop device from Texas Instruments.

• Features: direct clear (CLR) input and a complementary output from each flip-flop
• Features: Clear and preset are independent of the clock and accomplished by a low-level @ the appropriate input.
• Trigger: edge-triggered, meaning that it changes state either @ the rising edge or falling edge of the clock signal.
• Description: dual JK flip-flops, which are designed to toggle based on their input state when the clock transitions from high to low.
• Operating Voltage Range: 4.75 V to 5.25 V
• Package: 16-pin, small-outline package
