The registers are triggered by a positive transition of the positive clock (CLK) input.
A high on the Master Reset (MR) asynchronously resets all registers so that the Q outputs go LOW.
The differential input structures are clamped so that the inputs of unused registers can be left open without upsetting the bias network of the devices.
The clamping action will assert the /D and the /CLK sides of the inputs.
Because of the edge-triggered flip-flop nature of the devices, simultaneously opening both the clock and data inputs will result in an output which reaches an unidentified but valid state.
The fully differential design of the devices makes them ideal for very high frequency applications where a registered data path is necessary.
