Note 1:  The "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings.The "Recommended Operating Conditions" table will define the conditions for actual device operation.

  These DM74164 8-bit shift registers feature gated serial inputs and an asynchronous clear. A LOW logic level at either serial input inhibits entry of the new data, and resets the first flip-flop to the LOW level at the next clock pulse, thus providing complete control over incoming data. A HIGH logic level on either input enables the other input, which will then deter-mine the state of the first flip-flop. Data at the serial inputsmay be changed while the clock is HIGH or LOW, but only information meeting the setup and hold time requirements will be entered. Clocking occurs on the LOW-to-HIGH level transition of the clock input. All inputs of DM74164 are diode-clamped to minimize transmission-line effects.
