6-BIT REGISTER
DIFFERENTIAL DATA CLOCK
DESCRIPTION
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 0.01
F
capacitor.
