      NOTES:
      1. Stresses greater than those listed under ABSOLUTE MAXIMUM RAT-
      INGS may cause permanent damage to the device. This is a stress rating
      only and functional operation of the device at these or any other conditions
      above those indicated in the operational sections of this specification is
      not
      implied. Exposure to absolute maximum rating conditions for
      extended periods may affect reliability. No terminal voltage may exceed
      V
      CC
      by +0.5V unless otherwise noted.

      The D flip-flop data inputs.
      When the clear input is LOW and
      OE
      is
      LOW, the Q
      I
      outputs are LOW. When
      the clear input is HIGH, data can be
      entered into the register.
      Clock Pulse for the Register; enters
      data into the register on the LOW-to-
      HIGH transition.
      The register 3-state outputs.
      Clock Enable. When the clock enable is
      LOW, data on the D
      I
      input is transferred
      to the Q
      I
      output on the LOW-to-HIGH
      clock transition. When the clock enable
      is HIGH, the Q
      I
      outputs do not change
      state, regardless of the data or clock
      input transitions.
      Output Control. When the
      OE
      input is
      HIGH, the Y
      impedance state. When the
      OE
      input is
      LOW, the TRUE register data is present
      at the Y
      I
      outputs.
