6ĆBit D Register Differential
Data and Clock
The MC10E/100E451 contains six D-type flip-flops with single-ended
outputs and differential data inputs. The common clock input is also
differential. The registers are triggered by a positive transition of the
positive clock (CLK) input.
A HIGH on the Master Reset (MR) input resets all Q outputs to LOW.
The VBB output is intended for use as a reference voltage for
single-ended reception of ECL signals to that device only. When using for
this purpose, it is recommended that VBB is decoupled to VCC via a
0.01µF capacitor.
The differential input structures are clamped so that the inputs of
unused registers can be left open without upsetting the bias network of
the device. The clamping action will assert the D and the CLK sides of the
inputs. Because of the edge triggered flip-flop nature of the device
simultaneously opening both the clock and data inputs will result in an
output which reaches an unidentified but valid state. Note that the input
clamps only operate when both inputs fall to 2.5V below VCC.
