The MC10/100EP451 is a 6-bit fully differential register with common clock and single ended Master Reset (MR). It is ideal for very high frequency applications where a registered data path is necessary. All inputs have a 75k-ohm pulldown resistor internally. Differential inputs have an override clamp. Unused differential register inputs can be left open and will default LOW. When the differential inputs are forced to EE + 1.2 V, the clamp will override and force the output to a default state. When in the default state, and since the flip-flop is edge triggered, the output reaches a determined, but not predicted, valid state.
The positive transition of CLK (pin 4) will latch the registers. Master Reset (MR) HIGH will asynchronously reset all registers forcing Q outputs to go LOW.
The 100 Series contains temperature compensation.
