BLOCK DIAGRAM
DESCRIPTION
The SY10/100E241 are 8-bit shiftable registers designed
for use in new, high-performance ECL systems. Unlike the
E141, the E241 features internal data feedback organized
such that the SHIFT control overrides the HOLD, /LOAD
control. Thus, the normal operations of HOLD and LOAD
can be toggled with a single control line without the need for
external gating. This configuration also enables switching
to scan mode with the single SHIFT control line.
The eight inputs D0–D7 accept parallel input data, while
S-IN accepts serial input data when in shift mode. Data is
accepted a set-up time before the rising edge of CLK.
Shifting is also accomplished on the rising clock edge. A
HIGH on the Master Reset pin (MR) asychronously resets
all the registers to zero.
