designed for use in new, high-performance ECL systems.
The E141 performs serial/parallel in and serial/parallel out,
shifting in either direction. The eight inputs D
parallel input data, while DL/DR accept serial input data for
left/right shifting.
of operation: Load, Hold, Shift Left and Shift Right, as
shown in the Truth Table. Input data is clocked into the
register on the rising clock edge after meeting the minimum
set-up time. A logic HIGH on the Master Reset (MR) pin
asynchronously resets all the registers to zero.
