The SY10/100E451 offer six D-type flip-flops with single-
ended outputs and differential data and clock inputs,
designed for use in new, high-performance ECL systems.
The registers are triggered by the rising edge of the CLK
input.
A logic HIGH on the Master Reset (MR) input resets all
outputs to a logic LOW. The V
BB
output is provided for use
as a reference voltage for single-ended reception of ECL
signals to that device only. When used for this purpose, it
is recommended that V
BB
is decoupled to V
CC
via a 0.01µF
capacitor.

1. V
CMR
is referenced to the most psitive side of the differential input signal. Normal operation is obtained when the “HIGH” input is within the V
CMR
range
and the input swing is greater than V
