description/ordering information (continued)
These devices are positive-edge-triggered flip-flops with direct clear (CLR) input. Information at the data (D)
inputs meeting the setup time requirements is transferred to the Q outputs on the positive-going edge of the
clock pulse. Clock triggering occurs at a particular voltage level and is not directly related to the transition time
of the positive-going pulse. When the clock (CLK) input is at either the high or low level, the D-input signal has
no effect at the output.
These devices are fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the
outputs, preventing damaging current backflow through the devices when they are powered down.
