3.3V / 5V ECL 6-Bit
Differential Register with
Master Reset
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 75 k
W 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 < V
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.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
