The SN74HC112N is a dual negative-edge-triggered J-K Flip-flop with clear and preset. 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 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. This versatile flip-flop performs as toggle flip-flop by tying J and K high.

• Outputs can drive up to 10 LSTTL loads
• 13ns Typical tpd
• ±4mA Output drive at 5V
• 1µA Maximum low input current
• 40µA Maximum low power consumption

The SN74LVC1G74DCTR is a single positive-edge-triggered D-type Flip-flop is designed for 1.65 to 5.5V VCC operation. A low level at the preset (PRE) or clear (CLR) input sets or resets the outputs, regardless of the levels of the other inputs. When PRE and CLR are inactive (high), data at the data (D) input meeting the setup time requirements is transferred to the outputs on the positive-going edge of the clock pulse. Clock triggering occurs at a voltage level and is not related directly to the rise time of the clock pulse. Following the hold-time interval, data at the D input can be changed without affecting the levels at the outputs. This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
