1 / 18 page SN54HC112, SN74HC112 DUAL JK NEGATIVEEDGETRIGGERED FLIPFLOPS WITH CLEAR AND PRESET SCLS099F − DECEMBER 1982 − REVISED SEPTEMBER 2003 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Wide Operating Voltage Range of 2 V to 6 V D Outputs Can Drive Up To 10 LSTTL Loads D Low Power Consumption, 40-µA Max ICC D Typical tpd = 13 ns D ±4-mA Output Drive at 5 V D Low Input Current of 1 µA Max description/ordering information The ’HC112 devices contain two independent J-K negative-edge-triggered flip-flops. A low level at the preset (PRE) or clear (CLR) inputs sets or resets the outputs, regardless of the levels of the other inputs. When PRE and CLR are inactive (high), data at the J and K inputs meeting the setup time requirements are transferred to the outputs on the negative-going edge of the clock (CLK) pulse. Clock triggering occurs at a voltage level and is not directly related to the fall time of the CLK pulse. Following the hold-time interval, data at the J and K inputs may be changed without affecting the levels at the outputs. These versatile flip-flops perform as toggle flip-flops by tying J and K high.
